Relationships &
Connections Among Ideas

Master how the ACT tests your ability to trace cause and effect, comparisons, and sequential reasoning across reading passages.

ACT Reading

What Are Relationships in a Passage?

Every reading passage is built from ideas that connect to each other. The ACT asks you to identify how one idea relates to another: does it cause it, contrast with it, support it, or follow from it?

Five Core Relationship Types

Cause & Effect

One event or idea produces or leads to another

Compare & Contrast

Similarities or differences between two ideas

Sequence

Chronological or logical order of events

Problem & Solution

A challenge is presented, then a resolution follows

Claim & Evidence

An assertion supported by facts, examples, or reasoning

Why Does the ACT Test This?

The ACT Reading section is not just about finding facts. Roughly 20-25% of questions require you to understand how ideas relate across sentences, paragraphs, or the entire passage. These questions test critical thinking, not memorization.

The Signal Word Framework

Cause & Effect: The Most Tested Type

Cause-and-effect questions ask you to identify why something happened or what resulted from an event. Authors don't always state these relationships directly: sometimes the cause is implied across several sentences.

1

Explicit signals: "because," "as a result," "consequently," "therefore," "due to"

2

Implicit signals: Two events described in sequence where one logically triggers the other

3

Reversed order: The effect may appear before the cause in the text: "The city flooded [effect] after the dam collapsed [cause]."

Compare & Contrast: Spotting Differences

Contrast questions are the second most common type. The ACT loves to ask how two viewpoints differ or what two subjects have in common. Look for structural clues in the passage.

Comparison (Similarity)

"similarly," "likewise," "both," "in the same way," "just as"

Contrast (Difference)

"however," "on the other hand," "unlike," "whereas," "but"

Explicit vs. Implicit Connections

	Explicit Connections	Implicit Connections
Definition	Stated directly with signal words	Suggested through context and logic
Difficulty	Easier to locate in text	Requires inference and reasoning
Example	"Because of the drought, crops failed."	"The drought lasted months. Farmers abandoned their fields."
Question Phrasing	"According to the passage..."	"The passage suggests..." / "It can be inferred..."
Strategy	Scan for keywords, underline	Read surrounding context, connect events

The R.I.S.E. Method

R

Read the question stem carefully. Identify what type of relationship is being asked about: cause, contrast, sequence, etc.

I

Identify the key ideas. Find the two (or more) ideas the question asks you to connect. Note the paragraph and line numbers.

S

Scan for signal words. Look for transition words or phrases that reveal how the ideas connect.

E

Evaluate each answer choice. Eliminate choices that reverse the relationship, overstate it, or describe a relationship that doesn't exist in the passage.

Worked Example: Cause & Effect

Question: According to the passage, what was the primary cause of small businesses closing downtown?

1

Identify the chain: Factory relocated → foot traffic declined → businesses closed

2

Signal word: "resulted in" explicitly connects relocation to declining foot traffic

3

Correct answer: The loss of foot traffic from factory workers (the immediate cause, not the relocation itself)

Worked Example: Contrast

Question: The passage presents Dr. Alvarez and Dr. Keller as holding contrasting views primarily about:

Dr. Alvarez

Sudden event, single cause (asteroid impact)

Dr. Keller

Gradual decline, multiple causes (volcanism)

Worked Example: Implicit Connection

Question: The passage implies that the Great Migration contributed to which development?

1

No signal word: There is no "because" or "as a result" linking migration to the Harlem Renaissance

2

Logical chain: Migration to Northern cities → concentration of Black cultural communities → artistic flourishing

3

Answer: The flourishing of African American arts and culture (the Harlem Renaissance). The passage implies the connection through juxtaposition.

Mapping Relationships in a Passage

Common Mistakes to Avoid

✕ Reversing the Relationship

Confusing the cause with the effect: picking "X because of Y" when the passage says "Y because of X"

✕ Overgeneralizing

Choosing an answer that claims a stronger connection than the passage supports: "always" instead of "sometimes"

✕ Inventing a Connection

Using outside knowledge to create a link not present in the passage: stick to what the text actually says or implies

Decoding Question Stems

When You See...	The Relationship Is...	Strategy
"as a result of" / "led to"	Cause & Effect	Trace the chain of events
"in contrast to" / "differs from"	Compare & Contrast	Find both sides, note differences
"before" / "following" / "sequence"	Sequence	Map the chronological order
"in order to address" / "solution"	Problem & Solution	Locate the problem, then the fix
"supports" / "evidence for"	Claim & Evidence	Match claim to its supporting detail

Question 1 of 5

"The introduction of the printing press in the 15th century dramatically reduced the cost of producing books. As a result, literacy rates across Europe began to rise steadily over the following century, enabling a broader public to engage with scientific and philosophical texts."

▼ Tap to read passage

The passage establishes which relationship between the printing press and literacy rates?

The signal phrase "as a result" directly establishes a cause-and-effect relationship. The printing press (cause) led to rising literacy (effect).

Question 2 of 5

"Dr. Patel argued that remote work increases employee productivity by eliminating commute stress. However, Dr. Yamamoto countered that remote work often leads to isolation and blurred work-life boundaries, which can ultimately decrease long-term performance."

▼ Tap to read passage

The word "however" signals that the relationship between the two researchers' views is one of:

"However" is a classic contrast signal word. Dr. Patel sees increased productivity; Dr. Yamamoto sees decreased performance. These are opposing conclusions.

Question 3 of 5

"By the late 1800s, overcrowded tenements and unsanitary conditions in New York's Lower East Side had become a public health crisis. Journalist Jacob Riis documented these conditions in his 1890 book, which shocked the public and prompted city officials to pass new housing regulations."

▼ Tap to read passage

Which relationship structure best describes this passage?

The passage presents a problem (overcrowded, unsanitary tenements) and a solution (Riis's journalism leading to housing regulations). This is a classic problem-and-solution structure.

Question 4 of 5

A passage states: "The coral reefs were bleaching at alarming rates. Marine biologists discovered that rising ocean temperatures had weakened the symbiotic algae living within the coral." The phrase "had weakened" indicates what type of implicit relationship?

The past perfect "had weakened" shows that rising temperatures (cause) damaged the algae (effect), which then led to coral bleaching. This is a causal chain, even without an explicit "because."

Question 5 of 5

"First, the committee reviewed the environmental impact study. Then, they held three public hearings to gather community input. Finally, after weighing both the data and public opinion, the committee voted to approve the project with modifications."

▼ Tap to read passage

The signal words "first," "then," and "finally" establish what type of relationship among the committee's actions?

"First," "then," and "finally" are sequence signal words. They indicate chronological order. While there may be causal links between steps, the question specifically asks about the signal words, which mark sequence.
