Generate comprehension questions that actually test different levels of understanding, not ten variations on 'what happened'

Generate reading comprehension questions from the passage below, spread across genuinely different levels of understanding rather than ten questions that all just test recall of what happened.

PASSAGE
A 600-word excerpt from a science journalism article on why octopuses are considered unusually intelligent despite short lifespans.

WHAT THIS IS FOR
Practicing for a standardized reading comprehension section that mixes detail, inference, and author's-purpose questions.

QUESTION LEVELS AND HOW MANY OF EACH
3 literal, 4 inferential, 2 evaluative.

Build questions at three distinct levels, matching the counts I specified: (1) literal — answerable by pointing to one specific sentence or detail in the passage; (2) inferential — requires connecting two or more parts of the passage that aren't stated together, or reading between the lines of something implied but not said outright; (3) evaluative — requires a judgment about the passage itself, like identifying an author's assumption, a weakness in an argument, or what evidence would change the conclusion. Label each question with its level so I know what kind of thinking it's testing. For every question, write an answer key entry that doesn't just give the answer but names exactly where in the passage it comes from (a quote or paraphrase) so I can check my reasoning, not just my final answer. For inferential and evaluative questions specifically, the answer key must explain the reasoning chain, not just assert the conclusion — if a question requires connecting two facts, name both facts and how they connect.

Do not write an evaluative question that actually only requires locating information (a common failure mode where a question is labeled "analyze" but is answerable straight from the text) — if you can't construct a genuine evaluative question from this passage, say so and tell me why rather than mislabeling a recall question to hit the count.

Output as three labeled sections (Literal, Inferential, Evaluative), each with numbered questions, followed by a separate answer key section in the same order.
