Select the correctly punctuated quotation. According to Dr. Brock at the Amazon Institute, "capybaras have webbed feet for swimming and can even sleep underwater by keeping their nose just above the surface for breathing." According to Dr. Brock at the Amazon Institute, "Capybaras have webbed feet for swimming and can even sleep underwater by keeping their nose just above the surface for breathing." "According to Dr. Brock at the Amazon Institute," capybaras have webbed feet for swimming and can even sleep underwater by keeping their nose just above the surface for breathing. "According to Dr. Brock at the Amazon Institute, capybaras have webbed feet for swimming and can even sleep underwater by keeping their nose just above the surface for breathing."

The correctly punctuated quotation seems to be the first one:

According to Dr. Brock at the Amazon Institute, "capybaras have webbed feet for swimming and can even sleep underwater by keeping their nose just above the surface for breathing."

Explanation:

We can easily eliminate the last two options, since their use of quotation marks is completely wrong. Quotation marks are supposed to establish, so to speak, where the quote begins and where it ends. That is, they are supposed to show which words belong to the person being mentioned, separating them from the author's words. In the last two options, the marks are including words that were not said by Dr. Brock.

Now, when it comes to the first two options, we need to be careful because they are very similar. They are both using the quotation marks correctly. They also include the period before the last quotation mark, which is also correct. The difference between them seems to be only the capitalization of "Capybaras" in the second one. Such capitalization is unnecessary, which is why I believe the first option is the best choice.

you need to make an explanation. so, since you did not include one, so no one, and i mean no one can unfortunately you,
