“Diligently” means in an way that is efficient and hardworking, so "dililgently" makes the most sense in the sentence and is the correct answer.

“Bucolic” means related to the countryside.

“Illicit” means forbidden or unlawful.

“Disparaging” means critical or reproachful, and is most often used to describe things that are said.

“Steadfast” is synonymous with loyal.

“Amiable” means demonstrating a warm and friendly manner.

The structure of the sentence informs us that the paramedics were in some way shocked or surprised to arrive somewhere and find they were not needed. The answer choice that most clearly matches this definition is "incredulous," which means showing disbelief. Amiable and ecstatic are both associated with positive feelings. Amiable is friendly or pleasant and ecstatic is very happy. Diminished means reduced and could possibly fit here, but incredulous is a much better answer. Intrepid means adventurous.

The use of the words predatory and rapacious, which both relate to viciousness and destruction provides the context for the rest of the sentence. As Attila is predatory and rapacious, we know that his contemporaries must not have described as benevolent or affable, as these words mean good intentioned and friendly respectively. Munificent and lavish both relate to having a great deal of money: munificent means generous, and lavish means fancy or expensive. As the sentence makes no reference to Attila’s wealth, we can eliminate these options. This leaves only lupine, which means wolf-like. As wolves have historically be considered both predatory and rapacious this answer choice is the most correct.

This is a two-clause sentence, where the clues in the second clause help you solve the blank in the first clause. The second clause pertains to the number of legal cases brought before the courts so you know that the word in the first clause must relate to the legal system. Altruistic means an attitude of giving selflessly and would most likely be used in relation to charity. Indolent and lethargic both mean lazy and could not be applied to something so time consuming as going to court. Soporific refers to the experience of sleepiness or being tedious. Litigious, which means inclined to take legal action is by far the best fit.

You know from the context of the question that the scholars are looking back into the past. You can also infer from the fact that they are European scholars means they would think positively of the period of time when European philosophy had first flourished. Magnanimously means very kind or generous, and philanthropically refers to showing charitable concern for others. Neither of those words fits comfortably within the sentence. Derisively (show contempt) and disdainfully (show disgust) both refer to the expression of negative opinions; they do not satisfy what we can assume is true of the early Renaissance scholars. Only wistfully which means to be pensive, and yearn for something lost works within this sentence.
