caffeine and sleep, which is an informative purpose. Option A is
incorrect because there is no personal anecdote. Option C is
incorrect because the statement does not directly urge the
reader to stop drinking caffeine. Option D is incorrect because
the chemical structure is not discussed.

that describes the process of photosynthesis, including the
roles of chlorophyll, sunlight, and carbon dioxide?

RATIONALE: The main idea encompasses the entire process of
photosynthesis. Options A, B, and D are supporting details, not
the main idea.
Question 3: A student is reading a passage about the water
cycle. The passage states, "Evaporation occurs when water
changes from a liquid to a gas." Based on this information,
which of the following is a logical conclusion?
A. Evaporation only happens in the ocean.
B. Water vapor is a liquid.
C. Evaporation requires an input of energy.
D. Condensation is the same as evaporation.
CORRECT ANSWER: C
RATIONALE: The passage implies that evaporation involves a
change of state, which requires energy. Option A is too narrow.
Option B is incorrect because water vapor is a gas. Option D is
incorrect because condensation is the opposite process.

the following details from the passage would best support the
idea that the small intestine is the primary site of nutrient
absorption?

B. The small intestine has villi and microvilli that increase
surface area.

C. The small intestine connects to the stomach.
D. The small intestine produces some enzymes.
CORRECT ANSWER: B

but do not directly support the idea of absorption as strongly as
B.
