found in both freshwater and marine environments, possess dense, water - repellent fur which aids in insulation. often seen floating on their backs, they skillfully use tools, like rocks, to crack open shellfish. their social nature and endearing antics, such as holding hands while floating, have made them beloved animals worldwide.
which choice completes the text with the most logical and precise word or phrase?
a sleek, streamlined bodies
b glossy, gleaming bodies
c graceful, modernized bodies
d rough, dull bodies

Explanation:

The text describes an animal (likely an otter) in aquatic environments. "Sleek, streamlined bodies" logically fit as such body types help in swimming, aligning with the animal's aquatic habitat and behaviors (like floating, using tools in water). Option B's "glossy, gleaming" focuses on appearance not function. Option C's "modernized" is irrelevant for an animal's body. Option D's "rough, dull" contradicts the water - repellent fur and aquatic adaptability. So A is the best choice.

Answer:

A. sleek, streamlined bodies
