GMAT Expression of Ideas : (Expression) Questions
While researching a topic, a student has taken the following notes:
- Pineapple is a fruit that contains ascorbic acid, an essential nutrient for humans.
- Every \(\mathrm{100}\) grams (g) of pineapple contains \(\mathrm{48}\) milligrams (mg) of ascorbic acid.
- Many animals can make ascorbic acid in their bodies, but humans cannot.
- Humans must get ascorbic acid from foods, including fruits and vegetables.
- Ascorbic acid is also known as vitamin C.
The student wants to provide an example of a fruit that contains vitamin C. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Humans cannot make ascorbic acid in their bodies, but they can get it from foods, such as fruits, for example.
Vitamin C, also known as ascorbic acid, can be found in pineapple as well as other fruits.
Since humans cannot make vitamin C in their bodies, they must get it from food.
Many animals can make ascorbic acid, which is also known as vitamin C, in their bodies, but humans cannot.

Provide Passage Architecture & Core Elements
Main Point: Pineapple is a fruit source of ascorbic acid (vitamin C), which humans must obtain from foods since they cannot produce it themselves.
Argument Flow: The notes begin by establishing pineapple as a source of ascorbic acid and provide specific measurements. They then explain the broader context—while animals can produce this nutrient, humans cannot and must get it from foods like fruits and vegetables. Finally, they clarify that ascorbic acid is the same as vitamin C.
Step 2: Interpret the Question Precisely
What's being asked? The student wants to provide an example of a fruit that contains vitamin C, and we need to choose which option most effectively accomplishes this specific goal.
What type of answer do we need? A statement that successfully gives a concrete example of a fruit containing vitamin C, using the information from the notes effectively.
Any limiting keywords? "Most effectively" means we need the choice that best accomplishes the goal, and "uses relevant information from the notes" means the answer should draw from the provided research.
Step 3: Prethink the Answer
- The student's goal is very specific—to provide an example of a fruit that contains vitamin C
- The right answer should:
- Actually name a specific fruit (not just talk about fruits in general)
- Clearly state that this fruit contains vitamin C
- Connect back to the research notes provided
- From our notes, we know pineapple is specifically mentioned as a fruit containing ascorbic acid, and we're told that ascorbic acid is the same as vitamin C
- The right answer should mention pineapple as a concrete example of a fruit containing vitamin C
Humans cannot make ascorbic acid in their bodies, but they can get it from foods, such as fruits, for example.
- Talks about humans needing ascorbic acid from foods like fruits "for example"
- Doesn't actually name any specific fruit
- Fails to accomplish the goal of providing an example of a fruit containing vitamin C
Vitamin C, also known as ascorbic acid, can be found in pineapple as well as other fruits.
- Specifically names pineapple as a fruit containing vitamin C
- Uses both terms from the notes (vitamin C and ascorbic acid)
- Directly accomplishes the student's goal by providing a concrete example
Since humans cannot make vitamin C in their bodies, they must get it from food.
- Focuses on the general need for humans to get vitamin C from food
- Doesn't provide any specific fruit example
- Misses the target completely—talks about the need rather than giving an example
Many animals can make ascorbic acid, which is also known as vitamin C, in their bodies, but humans cannot.
- Emphasizes the difference between animals and humans regarding ascorbic acid production
- Contains no fruit examples at all
