When something is contaminated, its purity is destroyed. For instance, when a factory empties waste directly into the water, that water is contaminated, or polluted. Such pollution stops it from being in its pure condition. The verb "contaminate" merely means pollute or make impure. The wrong option "destroy" really is too strong. Certainly, contamination destroys the purity of something, but really contamination is more about the polluting than the destruction itself. Therefore, it is a better option to select "pollute" instead of "destroy."

"Compile" means put together or assemble, so "assemble" is the correct answer. "Smash" means hit something very hard and cause it to break. "Avoid" means stay or keep away from someone or something. "Inflate" means increase or fill with air. "Educate" means instruct or teach.

To "quench" means to satisfy, particularly with relation to satisfying a thirst. So, "satisfy" is the correct answer. To hep you, "suspend" means pause or hang from a specified location, "refute" means demonstrate to not be true, "portray" means show or represent, and to "obliterate" means to completely destroy.

"Pursue" means chase or run after, so "chase" is the correct answer. To "polish" means to clean and make shiny. "Explain" means describe or provide more details that make something more understandable. "Obey" means listen to, comply, or listen to someone and comply with rules and directions they give you. "Correct," when used as a verb, means make right.

To "shrivel" means to become smaller, to wrinkle and lose size. To provide further help, "outline" means draw out a plan of; "enhance" means make better and larger; "antagonize" means annoy; "displace" means replace, move out the way. 

The general idea behind "thrusting" is pushing or shoving. This might tempt you to thinking of choosing "slap." However, this is not quite correct. Think of how we use the word "thrust." We might say, "He thrust himself out into the crowd." This means that he pushed his way into the crowd. We could also say, "He thrust the duck at her," meaning that he pushed the bird toward the other person. Someone could thrust an object into a bag, meaning that he or she shoved it into the bag. Thus, the best option among those given is "shove."

Notice that all of these options deal with walking or running in some way; However, to "stroll" is to walk in an aimless manner. When we stroll, we just "walk around" without anywhere in particular to go, often in a very slow manner. Thus, the best option is "wander." This best expresses this kind of walking (or, strolling)!

The word "detain" means to hold or to imprison. Because it can indicate imprisonment, you may be tempted to pick "condemn" or "torture," but these are not correct. Yes, condemned people can be imprisoned, and imprisoned people can be tortured; however, this is not the meaning of "detain." Thus, the best option is "hold." You could say, "I detained him for three hours in the room." This means that you kept the person in the room for that long—effectively "holding" him there.

The word "swell" means to grow larger. For example, if you have a "swollen" throat, you have a throat that is likely enlarged from illness. The word "swell" is also used informally to say that you are doing well. For example, to say, "I am doing swell," means, "I am doing very well!" The best option among those given here, however, is "grow."

The word "interrogate" comes from roots that mean to ask or to question. You could say, "He interrogated her for many hours, trying to discover the cause of the murder." This means that he asked the other person questions for hours to discover the murder's cause. The word "question" can be used as a verb. You could rewrite that sentence with just that basic replacement: "He questioned her for many hours, trying to discover the cause of the murder."
