Mournful is not one of your original choices. Mourning was one, but that does not work grammatically.Thanks.. My favorite answer is mournful but i have no idea about explanation
The test is for Turkish civil servants http://en.wikipedia.org/wiki/KPDS "The Foreign Language Examination for Civil Servants ) is an English language proficiency test, mostly taken by civil servants and military personnel. It is administered by ÖSYM in Turkey in order to evaluate the foreign-language skills, especially of governmental employees."The only thing that makes d) the right answer is logic. Indeed, when people mourn, they become withdrawn. Most people. Others, however, might become idle when they lose their spouse.
How was the task formulated - choose the best answer or choose the correct answer. If the latter, then it is not a fair task. If the former, it cannot be an objective one. Either way, I do not like this exercise.
If you take the question as a whole - both parts - then it is a question of understanding the vocabulary, not a matter of logic. There is no causal association between idle and she rarely comes out of her house and doesn't speak much to anybody. Withdrawn is the only choice that provides a causal link. It is a perfectly fair task, if it is intended to test vocabulary and comprehension.The only thing that makes d) the right answer is logic.
