which word belongs in the blank?
good
well
best
fairly

Mrs. Nguyen explained to the class that they did well on their achievement exams. Option B is correct.

"Well" is the best option to fill the blank due to the fact that it is an adverb and those type of words are intended to modify verbs. In this particular case. the "word" well is describing the performance in the exams. In other words, well is modifying the verb "did."

The adverb "well" is defined by the dictionary as "in a good or satisfactory way" and "in a thorough manner."

martians or other types of aliens represent a unique fear as opposed to zombies. vampires and other types of monsters.   in most sci-fi stories, aliens come from other worlds and have different or more advanced technology.   abductions and experimentation on human bodies that involve these technologies, or the use of these technologies against human beings and the use of unknown "powers", are a type of fear that's different from that of other types of monsters.
