Read the sentence:
he studied and studied…and studied all night long.
what does the ellipsis show?
a pause while reading the sentence
a passage of time while studying
a pause in studying
a new sentence

a passage of time while studying.

The first part of the sentence states that he studied, and the last part similarly continues to state that he studied. Therefore, we can assume that the ellipsis between the two sections of the sentence is intended to show that even though time passed, he continued to perform the same action: studying.

this question is grammatically incorrect and is illegible to me so i can not answer.
