Question

how does the \signs of intelligence\ section contribute to the overall meaning of the passage?
(a) the section explains that intelligent life is found everywhere, including in the ocean, air, and land.
(b) the section explains multiple ways intelligence can be determined when studying living things.
(c) the section states that intelligence is something that is learned, rather than something you are born with.
(d) the section states that intelligence is measured on the same scale regardless of species.

Explanation:

To solve this, we analyze each option:

• Option a: The passage's "Signs of Intelligence" section likely doesn't claim intelligent life is everywhere in those specific environments (ocean, air, land) as a main contribution.
• Option b: A "Signs of Intelligence" section would logically explain methods to determine intelligence in living things, which fits the purpose of such a section.
• Option c: The section's title doesn't suggest it focuses on whether intelligence is learned or innate.
• Option d: It's unlikely the section states intelligence is measured on the same scale across species, as different species have different cognitive abilities and measurement scales would vary.

Answer:

b. The section explains multiple ways intelligence can be determined when studying living things.
