Question

review the text.
we spot the long, daunting head as it emerges just above the dark river surface, only the dark eyes and nostrils showing. then, the creature half - slides, half - lumbers onto the bank, its gray scales stacked, armor - like, along its body and mighty tail.
the only place in the world where crocodiles and alligators coexist is here in the florida everglades. this animals sleek dark - gray skin, rather than tan or olive green, indicates that it is an alligator. in addition, it has a broad u - shaped nose, while most crocodile noses are v - shaped. it appears to be approximately eight feet long, typical for a female american alligator.
the mighty creature settles quietly into the spiky grass, stretching out its muscular body under the warmth of the afternoon sun.
which best shows that the authors purpose is to describe an alligator moving from the water to the bank?
the author provides facts like the only place in the world where crocodiles and alligators coexist.
the author uses concrete details like half - slides, half - lumbers, and gray scales stacked, armor - like.

Explanation:

To determine the correct option, we analyze the author's purpose of describing an alligator moving from water to the bank:

• The first option ("The author provides facts...") focuses on the coexistence of crocodiles and alligators, which is not related to describing the alligator’s movement.
• The second option ("The author uses concrete details...") includes descriptive phrases like "half - slides, half - lumbers" (describing the alligator’s movement onto the bank) and "gray scales stacked, armor - like" (describing its appearance during the movement). These concrete details directly support the purpose of describing the alligator’s transition from water to the bank.

Answer:

The author uses concrete details like half - slides, half - lumbers, and gray scales stacked, armor - like.
