"Bibulous" refers to a person who is fond of drinking. The context of the sentence provides clues that indicate that the individual in the sentence frequents bars or saloons and stays longer than a casual drinker.

"Tantamount" means equal in value or meaning, and the description of the way the linebacker hits the wide receiver in the sentence seems to indicate that the hit was uncalled for, or too harsh for the fact the receiver was out of bounds. This would indicate a comparison to a barbarous act, so “tantamount” fits to complete the sentence.

The sentence is structured to create a contrast between the “chaotic” state of the family’s move and the period before their new jobs start. The correct choice will be a word that means something similar to calm or tranquil, and so the correct choice is "halcyon."

The sentence calls for a word that describes the type of movements of a trapeze artist, specifically the ability to walk a tight rope or fly through the air. The word that most closely fits this description would be “nimble.”

The key phrase is “never short of words.” The semicolon here links two independent clauses of similar meaning.  “Loquacious” means talkative and is therefore the correct answer. "Outgoing" and "extroverted" both mean gregarious or to be fond of social interaction.  Though close to the right answer, these are not as good a fit as "loquacious."  Also, "outgoing" and "extroverted" have the same meaning and thus both can be eliminated.  There cannot be two right answers to a test question. 

The logic of this sentence requires a word that means “discouraged”. The introductory clause “despite all his efforts” is a key phrase. The word “crestfallen” means dejected or discouraged.

The key phrase is “having traveled to many nations.” The word “eclectic” means embracing various or different sources.

A simple word replacement helps figure out the answer to this question. As the “more generous friends” are annoyed by the subject’s manner, then go through word by word for all the answer choices. "Parsimonious," which means stingy and tight with money, is the only choice that works.

The correct answer here is "auspicious" because the rain clouds were a symbol of something good to come, as they would nourish and save the crops. The rain clouds may have been short-lived ("ephemeral"), but that would not benefit the crops; the rain clouds certainly were not thorough and studious ("sedulous"), and they may have appeared "menacing," but again, their menacing appearance would have no impact on the dry nature of the crops.

"Nondescript" means lacking distinguishing characteristics. A thief without traits that set her apart would be difficult to identify in a line-up.
