Question

According to the passage, similarities between marsupials and placentals will most likely be found in

• A. brain function
• B. brain anatomy
• C. maternal behavior
• D. the corpus callosum
• E. selection for intelligence

Answer 1

The correct option is A

brain function

The hint is in the line 'Yet it cannot be inferred that marsupials are thus deprived of such function.' and also the last line of the passage says that. They both mean to say that Brain anatomy though different, functions normally for both.
