To “ameliorate” a situation means to improve it, or to make it better, so "improve" is the correct answer. To “disprove” something means to prove that it is wrong or incorrect; "infer" means to come to a conclusion that requires a logical jump from one point to another that may not immediately be obvious; "carry" means transport by picking up in one's arms and walking around; and "antagonize" means provoke.

"Conform" means adhere to a set standard just as others do or match and agree, so "match" is the correct answer. As for the other answer choices, "forget" means lose the memory of; "aggrandize" means make seem more important or powerful than something or someone really is; "justify" means explain one's reasons for doing something; and "demean" means insult and degrade.

When one thing “necessitates” another, it requires that the latter thing happen. One event is said to “entail” another when the latter is a necessary consequence of the former. For instance, “Because it requires a good deal of mathematical thought, learning to program a computer almost always entails becoming proficient at certain types of mathematics as well.”

"Divest" and "deprive" both means to dispossess or take off. "Maintain" means to care for or keep up. "Wane" means to diminish or lessen. "Goad" means to egg on or incite. "Beguile" means to fool or charm. 

The word “concoct” most generally means to make by combining together a number of parts or ingredients. For instance, one could refer to a stew or a potion as a “concoction.” The word can take on the further meaning of something that has been put together untruthfully, as when someone concocts a story to cover up the truth. The word “fabricate” does literally mean to make, but it also can have the same negative sense of to come up with a false tale.
