Words like "lurk" are likely very familiar; however, to get such questions correct, it is helpful to think of expressions that you know. For instance, have you ever said, "It was lurking just under the surface of the water?" This means that the thing was hiding just under the water's surface. Sometimes, we also say that someone's ideas, plots, or emotions are "lurking" under the surface of his or her demeanor. In general, the idea of "lurking" is that of hiding.

Whenever something "deteriorates," its condition worsens.

The word "exude" comes from roots that literally mean "to sweat out." The general idea of "exuding" is that something "oozes" or steadily releases something into its environment. The word can be used, however, to describe people in a metaphorical manner. Here the "oozing" is more like the idea of beaming or radiating some kind of character trait. For example, you could say, "Thomas was so sure of himself that he exuded confidence."
