When their examinations are over, the children gleefully …… the books they had been reading. A. shelve B. sidetrack C. overthrew D. abandon

The correct answer is: D. abandon.

The word “abandon” means to give up or leave something completely. In this case, the children are so happy that their exams are over that they give up on the books they had been reading.

The other options are not as accurate. The word “shelve” means to put something away temporarily, but the children are not planning to come back to the books. The word “sidetrack” means to divert someone’s attention from something, but the children are not being distracted from the books. The word “overthrow” means to defeat or overthrow someone or something, but the children are not doing anything to the books.
