In the question given below, a sentence is given with three words in bold. Three answer choices are given each including three words that can replace the three highlighted words respectively. Select the option that gives the correct combination of the answer choices. In case, the sentence is correct as it is, select 'No improvement.' Flying squirrels often have incidents , since gliding at night can be easy without the advantage of landing lights. 1) Accidents, challenging, benefit 2) Mishaps, demanding, help 3) Blessings, difficult, Aid

The sentence talks about flying squirrels and how they glide at night. The use of 'easy' is incorrect in the sentence as the latter part of the sentence says that they do not have landing lights so it might not be easy to land at night; similarly, the word 'blessing' is also incorrect. Choice 1 fits in the sentence as it conveys a meaningful idea that flying squirrels meet with accidents as it is difficult to glide at night. Choice 2 also fits in the sentence as 'mishap'(means accident), 'demanding'(means difficult or challenging) and 'help' fit in the sentence contextually as well as grammatically.
