in this part of the selection, scientists were surprised that a baby octopus was
a hungry enough to eat a whole shrimp.
b smart enough to solve a hard problem.
c small enough to hide from a jellyfish.
d brave enough to hunt at night.
many scientists now agree that a grown octopus is a very intelligent animal. but some were surprised to find out just how intelligent a baby octopus is.
a baby octopus is not very strong. it cant catch food by itself. but some scientists were watching as one baby octopus showed an amazing type of behavior. it used a tool to catch a shrimp to eat. this little octopus looked for a long arm from a jellyfish. a jellyfish is another animal that lives in the sea. it has long arms that can catch food. the baby octopus used the arm of a jellyfish as a tool to catch a shrimp for dinner. it will do this until it is big enough to do the job by itself

Explanation:

The text states that many scientists knew grown - octopuses were intelligent, but were surprised at how intelligent baby octopuses are. It then gives an example of a baby octopus using a jellyfish arm as a tool to catch a shrimp, which shows it is smart enough to solve the problem of catching food. There is no mention of the baby octopus being hungry enough to eat a whole shrimp, small enough to hide from a jellyfish, or brave enough to hunt at night.

Answer:

B. smart enough to solve a hard problem.
