Scope & Specificity: Analyzing 'Main Idea' Answer Choices

1 of 10

What makes a 'main idea' answer choice 'too broad'?

An answer choice is too broad if it makes a claim that is more general than what the passage actually supports. It might cover the topic but include information or make assertions not found in the text.

What makes a 'main idea' answer choice 'too narrow'?

An answer choice is too narrow if it accurately states something from the passage, but only focuses on a single detail or one paragraph's idea, rather than the central idea of the entire text. It's a classic supporting detail trap.

Example: A passage details the life cycle of the monarch butterfly. Which answer is 'too broad'? A) The monarch butterfly's life cycle. B) The complex life cycles of all insects.

B) 'The complex life cycles of all insects' is too broad. The passage is only about the monarch butterfly, not all insects.

Example: A passage details the monarch butterfly's life cycle. Which answer is 'too narrow'? A) The monarch's migration to Mexico is an amazing feat. B) The monarch butterfly undergoes a multi-stage life cycle.

A) 'The monarch's migration to Mexico is an amazing feat' is too narrow. The migration is just one part of the butterfly's life cycle, which is the overall subject of the passage.

How can you use keywords in answer choices to identify scope issues?

Be wary of absolute words like 'all,' 'every,' 'never,' or 'always,' as they often make an answer choice too broad. Conversely, watch for overly specific names, dates, or terms from one section of the passage, as they might signal an answert hat is too narrow.

What is the 'Goldilocks' principle for selecting a main idea?

The correct main idea answer is 'just right.' It's not too broad (covering more than the passage) and not too narrow (covering only a small part). It accurately reflects the scope and focus of the entire passage.

A passage argues that Shakespeare's Globe Theatre was rebuilt using historically accurate methods. Why would 'The history of Elizabethan theater' be a poor main idea choice?

This choice is too broad. The passage is specifically about the rebuilding of one theater, the Globe, not the entire history of all Elizabethan theater.

Using the same Globe Theatre passage, why would 'The Globe's roof was made of water reeds' be a poor choice?

This choice is too narrow. It's a specific, factual detail about the construction materials, not the overall central idea, which is about the commitment to historical accuracy in the entire rebuilding process.

How can outlining the passage help you determine the correct scope for the main idea?

By jotting down the main point of each paragraph, you create a map of the passage's content. The correct main idea answer must be general enough to encompass all of these points without leaving any out.

If an answer choice contains information you don't remember reading, what should you suspect?

You should suspect that the answer choice is too broad or simply incorrect. A correct main idea answer will be entirely supported by information presented within the passage itself. Do not rely on outside knowledge.
