Hello!
In the first excerpt, I'm assuming that the underlined word that you are unsure of its meaning is cloy'd. This word means excessive sweetness, so the correct answer is C. overly sentimental.
In the second excerpt, the word we're looking for is probably half-impaired. Impaired means weakened, or damaged, so the correct answer is A. partially damaged.
In the third excerpt, the unknown word is loth, which means unwilling to do something, so the correct answer is B. reluctant or unwilling.
Hope this Helps! Have A Wonderful Day! :)
