Constructing Moral ArgumentsQuestion 1 of 20

A political philosopher argues: 'A progressive taxation system, in which wealthier individuals are taxed at a higher percentage of their income, is morally required for a just society.' The philosopher's argument rests on the premise that individuals do not have an absolute moral claim to their pre-tax income because their earnings are significantly influenced by societal factors (e.g., public education, infrastructure, legal system) beyond their individual effort.

An objector who believes in strong property rights wants to refute this argument. Which rebuttal is most directly aimed at the philosopher's central premise?

Progressive taxation discourages work and investment, ultimately harming the economy and making everyone, including the poor, worse off.

It is impossible to accurately calculate the exact portion of an individual's income that is due to societal factors versus personal effort.

A flat tax system, where everyone pays the same percentage, is fairer because it treats every dollar of income equally.

While societal factors contribute to success, individuals still have a fundamental right to the fruits of their own labor, regardless of how those fruits were enabled.

Question 1

An objector who believes in strong property rights wants to refute this argument. Which rebuttal is most directly aimed at the philosopher's central premise?

Progressive taxation discourages work and investment, ultimately harming the economy and making everyone, including the poor, worse off.
It is impossible to accurately calculate the exact portion of an individual's income that is due to societal factors versus personal effort.
A flat tax system, where everyone pays the same percentage, is fairer because it treats every dollar of income equally.
While societal factors contribute to success, individuals still have a fundamental right to the fruits of their own labor, regardless of how those fruits were enabled. (correct answer)

Explanation: When analyzing arguments in political philosophy, you need to identify the core premise and find which counterargument directly challenges that foundation rather than peripheral issues. The philosopher's central premise is that individuals lack absolute moral claims to their pre-tax income because societal factors significantly contribute to their earnings. This challenges the notion of complete individual ownership of one's income. Answer D directly confronts this premise by asserting that regardless of societal contributions, individuals retain fundamental rights to their labor's fruits. This creates a head-on collision between two competing moral frameworks: the philosopher's view that societal contribution weakens individual claims versus the objector's view that labor rights remain inviolate despite external enabling factors. D doesn't deny societal influence but argues it's irrelevant to the fundamental moral claim. Answer A shifts to consequentialist economic arguments about taxation's effects rather than addressing the moral premise about income claims. Answer B raises a practical measurement problem but doesn't challenge whether societal factors actually weaken moral claims to income. Answer C proposes an alternative tax system based on equal treatment but sidesteps the core question of whether individuals have absolute rights to pre-tax income in the first place. On philosophy exams, distinguish between responses that directly engage the logical foundation of an argument versus those that change the subject to practical concerns, alternative proposals, or tangential issues. The strongest philosophical rebuttal typically confronts the opponent's fundamental assumptions head-on.

Question 2

A moral argument is presented: Premise 1: Any action that causes a sentient being to suffer is morally wrong. Premise 2: Factory farming causes sentient beings (animals) to suffer. Conclusion: Therefore, factory farming is morally wrong.

An objector responds: 'This argument is flawed. If we accept Premise 1, then a dentist causing a patient temporary pain during a procedure is also morally wrong, which is absurd.' How can the original argument's proponent best rebut this objection?

By arguing that animal suffering is morally different from human suffering.
By insisting that the dentist's action is, in fact, morally wrong despite its benefits.
By modifying Premise 1 to specify that the suffering must be unnecessary or not consented to. (correct answer)
By claiming the objector is committing a straw man fallacy by misrepresenting the argument.

Explanation: The correct answer is C. The objection works by presenting a counterexample (dentistry) where the principle in Premise 1 seems to lead to an incorrect conclusion. The most effective rebuttal is to refine the moral principle to account for the counterexample. Modifying Premise 1 to include qualifications like 'unnecessary' or 'non-consensual' suffering neutralizes the objection about the dentist (whose actions are necessary and consented to) while preserving the argument's core thrust against factory farming (where suffering is for human convenience and non-consensual). A is a weak rebuttal because it introduces a complex new claim without addressing the logical problem in the original premise. B is implausible and involves 'biting the bullet' on an absurd conclusion, which weakens the overall position. D is incorrect because the objector is not misrepresenting the argument; they are correctly applying the stated premise and showing its problematic implications.

Question 3

Consider the following argument structure: (1) A just society ensures the fair distribution of social goods. (2) Access to high-quality education is a primary social good. (3) In Country X, access to high-quality education is largely determined by parental wealth. (4) Therefore, Country X is not a just society.

In this argument, what are the respective roles of statements (2) and (3)?

(2) is a normative claim, and (3) is the conclusion.
(2) is an empirical claim, and (3) is a normative claim.
(2) is a bridging premise, and (3) is an empirical premise. (correct answer)
(2) is the main moral principle, and (3) is a supporting principle.

Explanation: The correct answer is C. Statement (1) sets up the main moral principle. Statement (3) is an empirical premise—a factual claim about the state of affairs in Country X that can be tested with data. Statement (2) serves as a crucial bridge; it connects the general principle about 'social goods' in (1) to the specific empirical fact about 'education' in (3), allowing the conclusion to be drawn. Therefore, (2) is a bridging premise (or a definitional/classificatory claim that functions as a premise) and (3) is an empirical premise. A is incorrect because (3) is a factual claim, not the conclusion. B incorrectly identifies the types; (2) is more of a conceptual or normative claim (defining education as a social good), while (3) is empirical. D is incorrect because (3) is a factual observation, not a principle.

Question 4

To justify military intervention in another country, a leader argues: 'We must intervene because their government is committing severe human rights abuses against its people. We have a duty to protect the innocent from such atrocities.'

An objector wishes to use a deontological framework to argue against this intervention. Which of the following objections would be the strongest from that perspective?

The intervention is likely to cause more suffering than it prevents, as it could lead to a long and bloody civil war.
The intervention violates a strict moral rule against infringing on national sovereignty, which is a foundational principle of international law and order. (correct answer)
The true motivation for the intervention is likely to be securing access to the country's natural resources, not protecting human rights.
Our country has its own unsolved domestic problems, and we should focus on those before trying to police the world.

Explanation: The correct answer is B. A deontological framework focuses on moral rules, duties, and prohibitions, regardless of the consequences. The original argument is also framed in terms of a duty ('duty to protect'). A strong deontological objection would posit a conflicting, and perhaps overriding, duty or rule. The principle of national sovereignty serves as such a rule. This objection argues that the act of intervention is inherently wrong because it violates a fundamental rule, irrespective of its potentially good intentions or outcomes. A is a classic consequentialist objection, focusing on the negative outcomes, not on rules or duties. C questions the motive, which is relevant, but doesn't engage with the principles of the argument as directly as B. D is an argument about priorities and prudence, not a deontological prohibition.

Question 5

In this argument, what are the respective roles of statements (2) and (3)?

(2) is a normative claim, and (3) is the conclusion.
(2) is an empirical claim, and (3) is a normative claim.
(2) is a bridging premise, and (3) is an empirical premise. (correct answer)
(2) is the main moral principle, and (3) is a supporting principle.

Question 6

An objector who believes in strong property rights wants to refute this argument. Which rebuttal is most directly aimed at the philosopher's central premise?

Progressive taxation discourages work and investment, ultimately harming the economy and making everyone, including the poor, worse off.
It is impossible to accurately calculate the exact portion of an individual's income that is due to societal factors versus personal effort.
A flat tax system, where everyone pays the same percentage, is fairer because it treats every dollar of income equally.
While societal factors contribute to success, individuals still have a fundamental right to the fruits of their own labor, regardless of how those fruits were enabled. (correct answer)

Question 7

Consider the following moral argument: Premise 1: If a technology has the potential to create massive, unforeseeable, and irreversible negative consequences, we have a moral obligation to prohibit its development. Premise 2: Advanced artificial general intelligence (AGI) has the potential to create massive, unforeseeable, and irreversible negative consequences. Conclusion: Therefore, we have a moral obligation to prohibit the development of AGI.

Which of the following, if true, most seriously weakens the argument?

The same technology also has the potential to create massive, unforeseeable, and irreversible positive consequences, such as curing all diseases. (correct answer)
Prohibiting the development of AGI is practically impossible, as it could be developed in secret by rogue actors.
The term 'massive' is too vague to serve as a useful guide for moral action or public policy.
Many past technologies, like electricity or the internet, also seemed to have unforeseeable risks but ultimately proved beneficial.

Explanation: The correct answer is A. The argument's first premise establishes a sufficient condition for prohibition based only on potential negative consequences. This is an application of the precautionary principle. Option A fundamentally challenges this one-sided view by pointing out that the technology also has massive potential benefits. This forces a more complex moral calculus (e.g., a utilitarian cost-benefit analysis) and suggests that Premise 1 is too simplistic, thereby weakening the argument that the potential harms are sufficient on their own to justify a ban. B raises a practical objection about enforcement, but it doesn't undermine the moral conclusion that we ought to prohibit it. C criticizes the vagueness of a term, which is a minor weakness compared to the fundamental challenge in A. D offers historical counterexamples, but the proponent of the argument could claim that AGI is a unique case, making this objection less direct than A.

Question 8

A bioethicist argues for a ban on human reproductive cloning with the following argument: 'Cloning violates the clone's right to an open future. We all have a right to a life of our own, with a future that is not predetermined by the choices and expectations tied to a specific genetic predecessor. A clone, being genetically identical to another person, would live under the shadow of that person's life, which unduly constrains their autonomy and sense of self.'

Which of the following is the most significant objection to this line of reasoning?

Genetically identical twins naturally exist, and we do not consider their right to an open future to be violated. (correct answer)
The parents of any child, clone or not, have expectations that can constrain the child's sense of an open future.
The potential medical benefits that could be gained from studying human clones outweigh any concerns about an 'open future'.
A person's genetics do not completely determine their life path, as environmental factors play a significant role.

Explanation: The correct answer is A. The argument claims that having an identical genome to another person is the condition that violates the right to an open future. The existence of identical twins is a direct and powerful counterexample. Twins share a genome, yet they are considered distinct individuals, and it is not generally held that their right to an open future is inherently violated. This forces the bioethicist to explain what makes the situation of a clone morally different from that of a twin, thus weakening the original argument substantially. B and D point out that other factors also constrain one's future, which is true, but they don't directly challenge the core claim about the specific harm of a shared genome in the way A does. C shifts the argument to a consequentialist framework, which is a different line of reasoning rather than an internal critique of the 'open future' argument itself.

Question 9

A city council is debating a 'sin tax' on sugary drinks. A proponent argues: 'This tax is morally justified. It will discourage unhealthy consumption, leading to better public health outcomes and reduced healthcare costs for everyone. The goal is to produce the greatest good for the greatest number.' An opponent objects, stating that this tax unfairly burdens the poor, who consume these drinks at higher rates.

How could the proponent best incorporate the opponent's concern while still defending the tax on utilitarian grounds?

Argue that the poor are the ones who will benefit the most from improved health, so the tax is actually in their best interest.
Concede that the tax is regressive but propose using the tax revenue to fund health programs in low-income communities, creating a net benefit. (correct answer)
Insist that individual choices that lead to poor health are morally blameworthy, and thus the burden on the poor is their own responsibility.
Shift the justification for the tax from public health to the personal virtue of moderation, which everyone should cultivate.

Explanation: The correct answer is B. The objection raises a valid concern about distributive justice from within a broadly utilitarian framework (an unequal distribution of burdens might reduce overall utility). The strongest utilitarian response is to acknowledge the burden but show how the policy can be designed to create a net positive outcome for the affected group. By earmarking the revenue for programs that specifically help low-income communities, the proponent can argue that the overall utility for this group will increase, despite the regressive nature of the tax itself. This is a sophisticated utilitarian move that synthesizes the initial goal with the objection. A is paternalistic and dismisses the felt burden of the tax. C is a non-utilitarian, blame-oriented argument. D shifts to virtue ethics, abandoning the original utilitarian framework.

Question 10

A student constructs an argument: 'It is morally wrong to eat meat. This is because the process of raising animals for food is incredibly harmful to the environment. We have a moral duty to protect the environment.'

To make this argument deductively valid, which of the following implicit premises must be added?

Eating meat is not necessary for human survival or health.
Any action that is incredibly harmful to the environment is morally wrong. (correct answer)
There are alternative food sources that are not harmful to the environment.
Animals have a right to life that is violated when they are raised for food.

Explanation: The correct answer is B. The argument as stated has a gap. It moves from a factual claim ('meat production harms the environment') and a general duty ('we should protect the environment') to a specific moral prohibition ('eating meat is wrong'). To bridge this gap and make the argument deductively valid, a connecting premise is needed. Premise B provides this link directly: If any action harmful to the environment is wrong, and meat production is harmful, then meat production (and by extension, eating meat from it) is wrong. A and C are relevant considerations that might strengthen the argument or respond to objections, but they are not necessary for deductive validity. D introduces a completely different line of reasoning (animal rights) that is not part of the original environmental argument.

Question 11

Argument: 'Active euthanasia is morally permissible. The core of morality is respecting individual autonomy. If a competent adult, facing a terminal illness with unbearable suffering, autonomously decides to end their life, then respecting their autonomy means allowing active euthanasia. To deny them this choice is to disrespect their autonomy.'

Which of the following statements represents the strongest objection to the moral argument presented in the passage?

Many religions consider euthanasia to be a sin, so it should not be permitted in a pluralistic society.
Doctors take an oath to preserve life, so allowing them to perform euthanasia would violate their professional code.
The principle of autonomy must be balanced against other fundamental moral principles, such as the intrinsic value of human life, which active euthanasia may violate. (correct answer)
It is often difficult to be certain that a patient's request to die is fully autonomous and not influenced by depression or coercion.

Explanation: The correct answer is C. The original argument rests entirely on the principle of autonomy. The strongest philosophical objection challenges this foundation by introducing a competing, equally fundamental moral principle (the intrinsic value of life). This creates a direct conflict of values that the original argument does not resolve. D points to a serious practical/epistemic problem, but it doesn't challenge the core moral principle itself; it questions whether the conditions for applying the principle are ever met. B is an appeal to professional ethics, which is a relevant but narrower objection than a fundamental moral principle like the value of life. A is an appeal to religious authority, which is not a universally accepted basis for moral argumentation in secular ethics and is therefore a weaker objection in this context.

Question 12

A philosopher argues: 'Governments should not censor artistic expression. Doing so is a slippery slope. If we allow the censorship of one offensive artwork, it will inevitably lead to the censorship of controversial political speech, then mainstream opinions, and finally all dissent, resulting in a totalitarian state.'

What is the most common and effective criticism of this type of moral argument?

The argument makes an appeal to emotion by focusing on the fear of a totalitarian state.
The argument fails to provide strong evidence that the initial step will necessarily lead to the final, extreme outcome. (correct answer)
The argument commits an ad hominem fallacy by attacking the motives of those who support censorship.
The argument wrongly assumes that artistic expression and political speech are morally equivalent.

Explanation: The correct answer is B. The argument presented is a classic example of a slippery slope argument. The primary weakness of most slippery slope arguments is that they assert a causal chain of events without sufficient justification. The critic can effectively challenge the argument by questioning the claimed inevitability of this chain. One can argue that it is possible to draw a principled line, for example, between obscenity and political speech, preventing the slide down the slope. A is a possible criticism, but the core logical flaw is the unsubstantiated causal chain, not just the appeal to fear. C is incorrect as the argument does not attack any person's motives. D points to a potential distinction but doesn't address the core 'slippery slope' mechanism of the argument itself.

Question 13

Argument: 'It is morally permissible for a corporation to prioritize maximizing shareholder profit above all else.' Objection: 'This view is mistaken, because corporations have a social responsibility to consider the well-being of their employees, the community, and the environment, even when it reduces profit.'

Which of the following statements would be the most effective rebuttal for a proponent of the original argument to make against this objection?

By maximizing shareholder profit, corporations indirectly create the greatest good for society through job creation and economic growth. (correct answer)
The personal ethics of corporate executives are irrelevant to the function of the corporation itself.
Most corporate charters legally require executives to prioritize shareholder profit, so their hands are tied.
It is impossible for a corporation to accurately measure its impact on the community or the environment.

Explanation: The correct answer is A. The objection introduces the idea of broader social responsibilities (stakeholder theory). The most effective rebuttal from the original position (shareholder primacy, often associated with Milton Friedman) is to co-opt the objection's concern for social well-being. Rebuttal A argues that the way corporations fulfill their social responsibility is by maximizing profit, as this leads to the best overall societal outcomes. This directly counters the objection by providing an alternative mechanism for achieving the same desired end (social good), reframing profit-seeking as a moral good. C is an appeal to law, which doesn't fully address the moral question of what the law should be. D is a claim about measurement difficulty, which is a practical problem but doesn't defeat the moral principle of the objection. B is largely irrelevant to the core dispute about a corporation's responsibilities.

Question 14

Consider the argument: 'Claiming a moral right to unlimited free speech is incoherent. Speech is an action that has consequences, some of which can be profoundly harmful to others. Since we all accept that there is no general moral right to harm others, it follows that there can be no moral right to speech that harms others.'

To counter this argument, a defender of free speech would most need to demonstrate that:

The harms caused by speech are not as severe as physical harms.
There is a morally relevant distinction between the types of 'harm' caused by speech and the types of 'harm' that morality typically prohibits. (correct answer)
The intention of the speaker, not the effect of the speech, is the primary determinant of the action's moral worth.
Any attempt to regulate harmful speech will ultimately be abused by those in power to suppress dissent.

Explanation: The correct answer is B. The argument's strength hinges on the premise that the 'harm' from speech is morally equivalent to other types of harm we prohibit (like physical assault). The most direct way to attack the argument is to break this equivalence. A defender of free speech (like John Stuart Mill) would need to argue for a distinction—for example, between physical harm and emotional offense or psychological discomfort. If this distinction is morally significant, then the conclusion that harmful speech should be restricted does not follow from the premise that we restrict other harmful acts. A makes a quantitative comparison, but the original argument can still stand if speech causes some harm. C shifts the focus to intent, which is a different ethical framework and doesn't directly refute the consequentialist premise of the argument. D is a practical/slippery slope argument against regulation, but it doesn't refute the core philosophical claim that there is no right to harmful speech.

Question 15

Argument: 'Using genetic screening to select embryos for desirable traits (e.g., high intelligence) is morally wrong because it treats children as commodities designed to satisfy parental desires, rather than as persons to be accepted unconditionally.'

Which of the following philosophical concepts is most central to the moral principle being used in this argument?

The utilitarian principle of maximizing overall happiness.
The social contract theory's emphasis on mutually advantageous cooperation.
The Aristotelian concept of eudaimonia, or human flourishing.
The Kantian imperative to treat humanity never merely as a means, but always as an end in itself. (correct answer)

Explanation: When you encounter ethics questions about human dignity and moral treatment, look for arguments that focus on respecting persons as inherently valuable rather than as objects to be used. This argument condemns genetic screening because it treats potential children as "commodities designed to satisfy parental desires" rather than persons deserving unconditional acceptance. This reasoning directly mirrors Kant's categorical imperative, which demands we treat humanity "never merely as a means, but always as an end in itself." The argument suggests that selecting embryos for desirable traits reduces future children to means for fulfilling parental preferences, violating their inherent dignity as persons. This makes D correct. A is wrong because utilitarian thinking would actually support genetic screening if it maximized overall happiness—having more intelligent, healthy children could increase total well-being. The argument explicitly rejects this consequentialist approach by focusing on the wrongness of the treatment itself, not its outcomes. B misses the mark because social contract theory deals with political obligations and cooperative arrangements between rational agents, not parent-child relationships or embryo selection. C is incorrect because while Aristotelian eudaimonia concerns human flourishing, this argument isn't about what makes life go well. Instead, it's about respecting the fundamental dignity of persons regardless of their traits or potential for flourishing. Remember: When you see arguments condemning practices for "treating people as objects" or "using people," think Kantian ethics. Kant's emphasis on human dignity as an end-in-itself frequently appears in bioethics discussions about genetic engineering, surrogacy, and medical research.

Question 16

A philosopher uses an analogy to argue for open borders: 'A country's border is like the door to a public library. Anyone who agrees to follow the rules should be allowed to enter and benefit from its resources. To deny entry based on a person's place of birth is as arbitrary and unjust as a librarian denying entry based on a person's hair color.'

An opponent of this argument would most effectively point to which disanalogy between a country and a public library?

Public libraries are funded by taxes, whereas countries have complex economies.
Librarians have a duty to maintain a quiet environment, while governments have a duty to protect national security.
Unlike library patrons who eventually leave, immigrants often become permanent members of the political community, with rights to vote and shape its future. (correct answer)
Some people do not like to read, but everyone needs a country to live in.

Explanation: The correct answer is C. A strong attack on an argument from analogy identifies a relevant difference between the two things being compared that undermines the conclusion. The analogy draws a parallel between access to a library and access to a country. Option C points out a crucial difference: the nature of membership. Library patronage is temporary and transactional, while citizenship or residency is a deep, permanent form of membership that includes political rights and responsibilities. This difference is highly relevant to the question of whether entry should be unrestricted, thus making it a powerful disanalogy. B points to a real difference in duties, but one could argue that both institutions have rules for safety and order. A is a weak distinction, as countries are also funded by taxes. D is irrelevant to the moral logic of the analogy.

Question 17

A philosopher argues that cultural relativism—the view that moral truths are determined by the standards of a given culture—is an incoherent position. The argument is as follows: (1) If cultural relativism is true, then there are no universal moral standards that apply across cultures. (2) The principle of tolerance—that we ought to respect the practices of other cultures—is often cited as a reason to be a cultural relativist. (3) However, the principle of tolerance, if it is to be binding on all cultures, must itself be a universal moral standard. (4) Therefore, the justification for cultural relativism relies on a universal standard, which the theory itself denies is possible.

Which of the following statements best describes the type of objection this argument makes?

It argues that cultural relativism has dangerous practical consequences.
It argues that cultural relativism commits the naturalistic fallacy.
It argues that cultural relativism is based on a false empirical premise about cultural disagreement.
It argues that cultural relativism is self-contradictory. (correct answer)

Explanation: When you encounter arguments about the internal consistency of philosophical theories, you're often dealing with questions of logical coherence rather than practical outcomes or empirical facts. This argument demonstrates that cultural relativism contains an internal contradiction. The philosopher shows that cultural relativism cannot coherently justify itself. Here's the logical structure: Cultural relativism claims no universal moral standards exist, yet its primary justification—the principle of tolerance—must itself be a universal standard to have any force. If tolerance only applies within cultures that happen to value it, then it cannot serve as a reason for all cultures to adopt relativism. The theory undermines its own foundation by requiring the very thing it denies exists. Answer D captures this perfectly—the argument reveals cultural relativism as self-contradictory. Answer A is wrong because the argument focuses on logical inconsistency, not practical dangers or harmful consequences of believing relativism. Answer B misses the mark because the naturalistic fallacy involves deriving moral conclusions from descriptive facts about nature or human behavior, which isn't what's happening here. Answer C is incorrect because the argument doesn't challenge any empirical claims about whether cultures actually disagree; instead, it examines the logical structure of relativist reasoning. When studying philosophical arguments, always ask whether the criticism targets internal logical problems versus external consequences or factual assumptions. Self-contradiction arguments are common in philosophy—they show a theory cannot consistently maintain its own principles, which is often considered a decisive refutation.

Question 18

An argument is made that universities should divest their endowments from fossil fuel companies: Premise 1: The burning of fossil fuels causes climate change. Premise 2: Climate change will cause immense human suffering. Premise 3: One should not profit from activities that cause immense human suffering. Premise 4: Investing in fossil fuel companies is a way of profiting from the burning of fossil fuels. Conclusion: Therefore, universities should divest from fossil fuel companies.

An objector argues that this divestment is merely symbolic and will have no real effect on climate change, as other investors will simply buy the shares. How can the proponent of the argument best respond to this specific objection?

By arguing that even symbolic actions are morally important for signaling institutional values and inspiring broader social change. (correct answer)
By providing economic data showing that a large-scale divestment campaign could, in fact, depress the stock prices of fossil fuel companies.
By insisting that the conclusion follows logically from the premises, so the practical effectiveness of the action is morally irrelevant.
By claiming that the objector is cynical and fails to appreciate the university's moral leadership role.

Explanation: The correct answer is A. The objection focuses on the lack of direct causal efficacy of the recommended action. The argument itself, however, is based on a deontological-sounding principle (Premise 3: 'One should not profit...'). Such principles often concern the moral integrity of the agent, not just the consequences of their actions. Response A effectively defends the argument on these grounds. It reframes the action's purpose, shifting it from direct causal impact (which the objection targets) to an expressive or symbolic function, which is fully consistent with a moral argument based on not being complicit in wrongdoing. B attempts to refute the empirical claim of the objection, which might be difficult and shifts the debate to economics. C 'bites the bullet' in a way that sounds dogmatic and fails to engage with the substance of the objection. D is an ad hominem attack on the objector and doesn't address the point.

Question 19

By arguing that animal suffering is morally different from human suffering.
By insisting that the dentist's action is, in fact, morally wrong despite its benefits.
By modifying Premise 1 to specify that the suffering must be unnecessary or not consented to. (correct answer)
By claiming the objector is committing a straw man fallacy by misrepresenting the argument.

Question 20

To make this argument deductively valid, which of the following implicit premises must be added?

Eating meat is not necessary for human survival or health.
Any action that is incredibly harmful to the environment is morally wrong. (correct answer)
There are alternative food sources that are not harmful to the environment.
Animals have a right to life that is violated when they are raised for food.
