Rhetorical Synthesis Pattern - Explain Reason

Explaining why something happened or what its effect or significance is

In these Rhetorical Synthesis questions, the notes contain a cause-and-effect relationship, and the question asks you to pick the sentence that connects them. You're not just identifying a fact — you're choosing the answer that explains why something happened or what resulted from it. The right answer always links two pieces: a reason and an outcome.

How to recognize it

The stem will use language like "explain an advantage of," "emphasize the significance of," "explain the origin of," or "present the significance of X to an audience unfamiliar with Y." Whenever the question asks you to show the connection between a cause and its effect — not just state one or the other — you're dealing with Explain the Reason.

How to approach it

Read the notes and identify the cause-effect pair. Usually one or two bullets establish the background (the cause or context), and another states the outcome or significance. Then check each answer choice: the correct one will explicitly link both halves. Wrong answers tend to state only the cause, only the effect, or get a key detail wrong.

Here's an example. The notes read:

While researching a topic, a student has taken the following notes:

• The 1918 influenza pandemic spread worldwide during World War I.
• Governments of several warring nations censored news about the outbreak.
• Spain, a neutral country, openly reported on the disease in its newspapers.
• Because reports were prominent in Spain, many people wrongly assumed the pandemic began there.
• As a result, the pandemic became popularly known as the "Spanish flu."

The question asks: The student wants to emphasize the role a misconception played in the naming of a disease. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A) The 1918 influenza pandemic unfolded during World War I. B) The 1918 pandemic became widely known as the "Spanish flu." C) Because wartime censorship hid outbreaks elsewhere while Spain's free press reported them, many wrongly believed Spain was the source, and the disease was called the "Spanish flu." D) Spain strictly censored reports about influenza, leading people to call the pandemic the "Spanish flu."

The question asks for the role a misconception played — that means you need both the misconception (people thought it started in Spain) and the reason behind it (censorship elsewhere, open reporting in Spain). Choice C delivers the full chain: censorship hid cases in warring nations, Spain reported openly, people assumed Spain was the origin, and the name stuck. Choice A provides background but no cause-effect link. Choice B gives only the name without explaining why. Choice D actually gets a fact wrong — it says Spain censored reports, when the notes say the opposite. The answer is C.

Notice how the hardest trap here isn't just a missing piece — it's a factual reversal. That's common in Explain the Reason questions: one choice will flip a critical detail.

Traps to watch for

• Effect without cause. A choice states the outcome (the name, the significance, the result) but never explains why it happened. It answers "what" but not "why."
• Cause without effect. A choice gives background or context but doesn't connect it to the outcome. It's accurate but incomplete.
• Factual reversal. One choice will sometimes swap or distort a detail — saying the opposite of what the notes state. If you haven't read the notes carefully, this one sneaks through.
• Vague connection. A choice implies a link but uses generic language ("helped solve a problem" or "influenced later developments") without stating the specific mechanism from the notes.

How the difficulty changes

Easier questions:

While researching a topic, a student has taken the following notes:

• NASA launched a large space telescope in 1990 to observe distant galaxies.
• The telescope orbits Earth.
• The telescope is named Hubble to honor astronomer Edwin Hubble.
• Edwin Hubble's work showed that the universe is expanding.

The question asks the student to explain the origin of the telescope's name. The cause-effect link is straightforward: the telescope was named to honor a specific person. One wrong answer gives the launch date and function, another mentions Hubble's discovery but never connects it to the naming. At this level, the chain is short and the right answer states it plainly.

Medium questions:

While researching a topic, a student has taken the following notes:

• In the late 1800s, large business trusts controlled prices and limited competition in industries such as oil, sugar, and railroads.
• By 1890, Standard Oil dominated about 90 percent of US oil refining.
• Critics argued that trusts hurt consumers and small businesses.
• The 1890 Sherman Antitrust Act prohibited contracts, combinations, or conspiracies in restraint of trade and made attempts to monopolize illegal.
• Early enforcement was uneven, but the law became a key tool in later trust-busting cases.

The question asks the student to present the significance of the Sherman Antitrust Act to an unfamiliar audience. Now you need to link the problem (trusts controlling markets) to the solution (the Act's provisions) in a way that explains why the Act mattered. One wrong answer gives only the problem, another gives only the Act's provisions without context, and a third offers a narrow statistic. The right answer connects both halves.

Harder questions:

While researching a topic, a student has taken the following notes:

• A small number of women earned medical degrees in the United States before 1870.
• Clarissa Dent was born in Vermont in 1843.
• She received an MD in 1868.
• Nora Hale was born in Pennsylvania in 1840.
• She received an MD in 1865.

The question asks the student to emphasize the historical significance of Clarissa Dent's graduation year. The notes never explicitly say "this is significant because..." — you have to connect the dots yourself. Dent graduated in 1868, which falls before 1870, making her one of the few women to earn an MD in that era. One wrong answer compares the two women's dates without explaining why either date matters. Another gives background about both women but skips the broader context. The right answer links the specific year to the historical rarity — and that synthesis is entirely on you.

Your approach on test day

1. Read the notes and identify the cause-effect pair: what happened, and why or what resulted.
2. Check the stem to see whether it asks for an explanation, a significance, or an advantage — all variations of the same thing.
3. Pick the choice that explicitly connects both halves. If a choice gives you only one side of the link, eliminate it.
4. Watch for factual reversals — re-read the notes if any choice seems close but slightly off.
