Similarities and Differences — Identify a similarity or difference between two texts. - SHSAT English Language Arts

SECTION 1

Why Comparing Texts Matters

Comparing things is something humans have done for thousands of years. Ancient scholars compared stories, myths, and histories to figure out what was true and what was made up. Today, comparing texts (looking at two pieces of writing side by side) is one of the most important reading skills you can develop. It helps you think critically and see ideas from more than one angle.

Ancient • Oral Storytelling Traditions

People compared myths and legends from different cultures to find shared lessons about bravery, honesty, and family.

1800s • Rise of Comparative Literature

Scholars began formally comparing novels, poems, and essays from different countries to understand how culture shapes writing.

1970s • Standardized Testing Emerges

Tests like the SHSAT started using paired passages. Students had to read two texts and answer questions about how the texts relate.

Today • SHSAT Paired-Passage Format

The current SHSAT includes paired reading passages. You must identify similarities and differences in topic, tone, purpose, and point of view.

On the SHSAT, you will see two passages grouped together. The test will ask you how these passages are alike or different. The big question this lesson answers is: How do you figure out what two texts share, and where they go in different directions?

SECTION 2

Core Principles of Comparing Texts

Before you start comparing, you need to know what to look for. Think of each passage as having several layers, like an onion. You can compare the outer layer (what the passage is about) or the deeper layers (how the author feels or what the author's goal is). Here are the key areas to focus on.

Topic & Subject Matter

What is each passage about? Two passages might both discuss space exploration, or one might be about space and the other about ocean exploration.

Author's Purpose

Why did the author write this? One author might want to inform (give facts), while another might want to persuade (change your mind).

Tone & Attitude

Tone is the feeling behind the words. One passage might sound excited and hopeful, while another feels serious and cautious.

Point of View & Perspective

Does the author support or oppose an idea? Two authors can write about the same topic but take opposite sides of a debate.

Evidence & Details

What facts, examples, or stories does each author use? The types of evidence an author chooses can reveal a lot about their approach.

✦

KEY TAKEAWAY

Think of comparing two texts like comparing two pizza restaurants. Both places sell pizza (that's the similarity in topic). But one restaurant uses thin crust and the other uses thick crust (that's a difference in approach). You wouldn't say they're completely the same or completely different — you'd notice both the overlap and the contrast. That's exactly what the SHSAT wants you to do with passages.

SECTION 3

Seeing Similarities and Differences

One of the best ways to organize your thinking is with a Venn diagram (two overlapping circles). The left circle holds details unique to Passage 1. The right circle holds details unique to Passage 2. The overlap in the middle holds what both passages share. The diagram below shows how this works.

This Venn diagram shows how two passages about space exploration can share a similar topic (the middle) while having different tones, evidence, and purposes (the outer sections).

Notice how both passages are about space exploration — that's the similarity. But Passage 1 is persuasive and emotional, while Passage 2 is informative and neutral — those are the differences. On the SHSAT, you won't draw a Venn diagram, but you can picture one in your mind as you read.

SECTION 4

How to Compare Two Passages Step by Step

The SHSAT doesn't just ask "Are these passages alike?" It asks specific questions, like "How would the author of Passage 1 most likely respond to the argument in Passage 2?" To answer these questions, you need a reliable method. Here is a four-step process you can use every time.

The Four-Step Comparison Method

Read & Summarize Each Passage

After reading each passage, write a quick mental summary: "This passage is about _____ and the author thinks _____." Keep it to one sentence per passage.

Identify the Comparison Category

Look at the question. Is it asking about topic, tone, purpose, point of view, or evidence? This tells you which layer of the passage to focus on.

Find Textual Evidence

Go back to both passages and find the specific sentences or phrases that support your answer. The right answer is always backed up by the text.

Eliminate Wrong Choices

Cross out answer choices that are only true for one passage, that aren't supported by the text, or that are too extreme. Pick the best remaining choice.

Follow these four steps every time you encounter a paired-passage comparison question on the SHSAT.

💡

SHSAT Tip

When you see a question that says "Both passages suggest…" or "Unlike the author of Passage 1, the author of Passage 2…," these are comparison questions. The wording tells you whether the question is about a similarity ("both") or a difference ("unlike").

SECTION 5

Types of Similarities and Differences

Not all comparisons are the same. Sometimes the SHSAT asks about big-picture ideas, and sometimes it asks about small details. The table below sorts the most common comparison categories into two groups: big-picture comparisons and detail-level comparisons.

Category	What to Ask Yourself	Example Question Stem
Topic / Subject	Are both passages about the same general subject?	"Both passages are mainly about…"
Central Idea / Theme	What is the main message of each passage?	"A central idea shared by both passages is…"
Author's Purpose	Does the author want to inform, persuade, or entertain?	"The author of Passage 1 writes to _____, while the author of Passage 2 writes to _____."
Tone / Attitude	What feeling do the word choices create?	"Unlike the tone of Passage 1, the tone of Passage 2 is…"
Evidence & Details	What kinds of facts, quotes, or examples does each author use?	"Which detail from Passage 2 would best support the claim in Passage 1?"
Point of View / Opinion	Do the authors agree or disagree on the issue?	"How would the author of Passage 1 most likely respond to the claim in Passage 2?"

Common comparison categories on the SHSAT

When you see a comparison question, quickly identify which category it falls into. This narrows your focus so you don't waste time rereading the entire passage.

SECTION 6

Worked Example: Two Passages About School Uniforms

Let's walk through a full example using two short passages about school uniforms. Read each passage, then follow the four-step method.

📝

Passage 1

School uniforms help students focus on learning instead of fashion. When everyone wears the same outfit, no one feels left out because of what they're wearing. Studies show that schools with uniform policies see fewer discipline problems. Uniforms also save families money over time. For these reasons, every school should adopt a uniform policy.

📝

Passage 2

School uniforms have been a topic of debate for decades. Supporters say uniforms create equality and reduce bullying. However, critics argue that uniforms take away students' ability to express themselves. Some research suggests that uniforms do not actually improve grades. The decision about uniforms is complicated, and both sides make valid points.

Question: How do the purposes of Passage 1 and Passage 2 differ?

Applying the Four-Step Method

1
Step 1 — Read & Summarize Each Passage

Passage 1 is about school uniforms and argues that every school should have them. Passage 2 is also about school uniforms but presents both sides of the debate without choosing one.

Passage 1: pro-uniform argument. Passage 2: balanced overview.
2
Step 2 — Identify the Comparison Category

The question asks about the "purposes" of the two passages. This falls under the Author's Purpose category. We need to figure out why each author wrote their passage.

Category: Author's Purpose
3
Step 3 — Find Textual Evidence

In Passage 1, the last sentence says "every school should adopt a uniform policy." The word "should" tells us the author is trying to persuade. In Passage 2, the last sentence says "both sides make valid points." This tells us the author is trying to inform by presenting a balanced view.

Passage 1 = persuade; Passage 2 = inform
4
Step 4 — Eliminate Wrong Choices & Select Answer

If we saw answer choices like (A) "Both passages try to persuade," we would eliminate it because Passage 2 doesn't try to persuade. If we saw (B) "Passage 1 persuades while Passage 2 informs," that matches our evidence. We'd select choice B.

Answer: The purpose of Passage 1 is to persuade readers that uniforms are beneficial, while the purpose of Passage 2 is to inform readers about both sides of the debate.

SECTION 7

Strengths, Traps, and Tips

The SHSAT test-makers create wrong answer choices that are designed to trick you. Knowing the most common traps will help you avoid them. Below is a table showing the traps and how to beat them.

Common Trap	What It Looks Like	How to Avoid It
One-Passage Answer	The answer choice is true for one passage but not the other.	Always check your answer against BOTH passages before selecting it.
Too Extreme	Uses words like "always," "never," or "completely opposite."	Be wary of extreme language. Correct answers usually use moderate words like "mostly" or "tends to."
Flipped Comparison	Says Passage 1 does what Passage 2 actually does, and vice versa.	Read carefully to make sure the right information matches the right passage number.
Outside Information	The answer sounds right based on what you already know, but it isn't in the text.	Only use information from the passages. Your background knowledge doesn't count.

Common answer traps and strategies for avoiding them

KEY TAKEAWAY

Imagine you're a detective comparing two witnesses' stories about the same event. You wouldn't just listen to one witness — you'd carefully check both stories, look for where they agree, and note where they disagree. That's exactly what you do with paired SHSAT passages. The text is your evidence — stick to it.

SECTION 8

Connecting to Advanced Reading Skills

Comparing two texts is a skill you'll use long after the SHSAT. In high school, you'll write essays that compare novels or historical documents. In college, you might analyze competing scientific studies. The skill gets more complex, but the foundation is the same.

SHSAT Level (Now)	Advanced Level (Later)
Identify whether two passages share the same topic.	Analyze how two sources frame the same issue differently based on cultural context.
Notice if one author persuades while the other informs.	Evaluate how an author's rhetorical strategies shape their argument's effectiveness.
Find evidence in the text that supports your comparison.	Synthesize evidence from multiple sources to build an original argument.
Pick the best answer from multiple choices.	Write a multi-paragraph comparative essay with a thesis statement.

How SHSAT comparison skills grow into advanced reading and writing

Mastering this skill now gives you a strong head start. The four-step method you learned in this lesson is the same thinking process used by advanced readers — they just apply it to harder texts.

SECTION 9

Practice Problems

Use the passages below to answer the five practice questions. Read both passages carefully before answering.

ℹ

Passage A

Honeybees are essential to our food supply. They pollinate about one-third of the food we eat, including fruits, vegetables, and nuts. In recent years, bee populations have declined sharply due to pesticides, habitat loss, and disease. If we do not take action to protect bees, the consequences for agriculture could be devastating. Everyone should support laws that ban harmful pesticides.

ℹ

Passage B

Honeybees play a major role in ecosystems around the world. Scientists have identified several threats to bee populations, including certain pesticides called neonicotinoids, the loss of wildflower habitats, and a parasite known as the Varroa mite. Researchers are studying different solutions, from breeding stronger bees to planting pollinator gardens. While the problem is serious, some experts believe that increased awareness has already led to positive changes.

Question 1: CONCEPTUAL

What is one similarity between Passage A and Passage B?

Show answer

Both passages are about honeybees and the threats they face. Passage A mentions pesticides, habitat loss, and disease. Passage B mentions neonicotinoids (a type of pesticide), habitat loss, and the Varroa mite. This shared topic — the decline of honeybee populations — is the main similarity.

Question 2: BASIC

How does the purpose of Passage A differ from the purpose of Passage B?

Show answer

Passage A is written to persuade. Its last sentence, "Everyone should support laws that ban harmful pesticides," directly calls the reader to action. Passage B is written to inform. It presents facts, names specific threats, and describes ongoing research without telling the reader what to do. The key evidence is the final sentence of each passage.

Question 3: INTERMEDIATE

How do the tones of Passage A and Passage B differ? Use evidence from each passage to support your answer.

Show answer

Passage A has an urgent, alarming tone. Words like "devastating" and "if we do not take action" create a sense of fear and urgency. Passage B has a more measured, hopeful tone. Although it calls the problem "serious," it ends on a positive note: "some experts believe that increased awareness has already led to positive changes." The word choices in each passage create very different emotional impacts.

Question 4: APPLIED

Imagine the author of Passage A reads Passage B. How would the author of Passage A most likely respond to the final sentence of Passage B ("some experts believe that increased awareness has already led to positive changes")?

Show answer

The author of Passage A would most likely argue that awareness alone is not enough. Since Passage A ends with a call for laws banning pesticides, its author believes that concrete government action is needed. The author might say that "positive changes" are a good start but that without stronger laws, bee populations will continue to decline. This answer is supported by Passage A's urgent tone and its specific demand for pesticide bans.

Question 5: CRITICAL THINKING

A student claims: "Passage A and Passage B completely disagree about honeybees." Is this claim accurate? Explain why or why not, using evidence from both passages.

Show answer

This claim is not accurate. The passages do not completely disagree — in fact, they agree on the main issue: honeybee populations are declining and the situation is serious. Both passages mention pesticides and habitat loss as threats. The difference is not in their facts but in their purposes and tones. Passage A argues for a specific solution (banning pesticides), while Passage B takes a broader, more balanced view. Saying they "completely disagree" is too extreme and ignores their shared subject and concern.

SUMMARY

Lesson Summary

Summary

When you compare two SHSAT passages, focus on five key areas: topic, author's purpose, tone, point of view, and evidence and details. Use the four-step method: read and summarize, identify the comparison category, find textual evidence, and eliminate wrong choices.

Remember to watch out for common traps, especially one-passage answers (true for only one text), too-extreme language, and flipped comparisons. Always base your answer on what the text actually says, not on outside knowledge. With practice, spotting similarities and differences will become second nature.
