The suffix "-cide" means related to killing and the prefix "reg-" means related to royalty or the king, so “regicide” is the killing of a king. To solve this analogy, you need to determine what “pesticide” is the killing of. The correct answer is “vermin,” which are small wild animals that damage crops or harm domesticated animals. "Pests" is a synonym of "vermin."

The relationship here has to do with the suffix "-ify". This suffix turns a noun or adjective (like "terror" or "intense") into a verb meaning to bring about a state of [adjective]. Similar to how "terrify" means cause to feel terror, "intensify" means to make more intense.

A rose typically has or consists of many petals, so we need to pick out an answer choice that describes a noun which typically has or consists of many teeth. “Dentistry” and “toothbrush” might each look like potentially correct answers because “teeth” can mean the bony, enamel-covered units in contained in the mouth and used for chewing. However, neither “dentistry” nor “toothbrush” are things that consist of many teeth, so neither can be the correct answer; however, “teeth” can also mean individual parts that project on a comb, gear, or saw. Considering it as falling under this definition, “zipper” makes sense as an answer, because the individual bits of a  zipper that interlock are called "teeth." So, just as a rose consists of petals, a zipper consists of teeth, so “zipper” is the correct answer.

The word "arrest" most commonly means catch a criminal and charge him or her with a crime; however, in this instance, you have to know the secondary meaning of "arrest," which is stop something. “Arrest” can mean stop whilst “begin” means start, so you need to pick out an answer choice that is an opposite of “virtue.” “Virtue” is a morally good character trait whereas “vice” is a morally bad character trait. To help, “disbelief” is mental rejection of something as untrue; “prosperity” is the state of being successful; “sacrifice” is the act of giving up something you want to keep; and “merit” is excellence or worth.

Since one meaning of "carp" is complain in an annoying way, "carp" and "complain" are synonyms. We thus need to pick out another answer choice in which the two words are synonyms. While "trout is to fish" may look like a potentially correct answer choice because "carp" as a noun refers to a type of fish and "trout" is also a type of fish, "trout is to fisherman" cannot be the correct answer because "trout" and "fisherman" are not synonyms. "Speak" and "utter" are synonyms, though, so the correct answer is "speak is to utter."

Since tango is a style or form of dance, we need to pick out an answer in which the first word is a style or form of the second word. While "painting is to impressionism" and "poem is to sonnet" may both look like correct answers, the words in these answers appear in the wrong order; instead of having the style come first and the category come second, they have the category come first and the style come second. "Jazz is to music," however, has its words in the correct order (style is to category), and since jazz is a style or kind of music, "jazz is to music" is the correct answer.

“Whisper” is a word that as a verb means speak very softly and as a noun means a very quiet act of speaking. So, if one whispers, one is being quiet, and we need to pick out an answer choice in which the first word is a manner of speaking and the second word an adjective describing that manner of speaking. While “holler is to loud” and “murmur is to blaring” might each look like a potentially correct answer, “murmur” is a word that when used as a verb means say something in a quiet, almost indistinct voice while “blaring” is an adjective that means loud. So, because “murmur” is not accurately described by “blaring,” “murmur is to blaring” cannot be the correct answer. “Holler,” however, when used as a verb, is used of a person and means shout, so “loud” is an accurate descriptor of “holler” just like “quiet” is an accurate descriptor of “whisper.” So, “holler is to loud” is the correct answer.

In this analogy, you need to know two secondary definitions of words. If "weather" is read as a noun meaning atmospheric phenomena like rain and snow, a storm is a type of weather, but none of the answer choices present a type of champion. "Weather" is here being used as a verb instead; to "weather" something means to endure it, as in the phrase "weather a storm." Similarly, "champion" is being used as a verb meaning promote. Just as you "weather" (endure) a storm, you promote a cause, so the correct answer is “cause.”

One could read "cork" as a verb, as one can "cork a bottle," to shut it, but in that case, none of the answer choices would work as verbs meaning close a jar. "Cork" can also be read as a noun meaning the small stopper that closes up a bottle. Using this definition, we need to pick out an answer choice that describes what closes up a jar. While "jam" might look like a good answer choice because a jar may be filled with jam, jam does not close up a jar, but instead represents potential contents of a jar. Since a lid closes up a jar just like a cork closes up a bottle, "lid" is the correct answer.

"Bestow" is a verb that means confer, and "award" is either the thing bestowed on something, or a synonym of "bestow" if it is used as a verb meaning give an award. We need to pick out an answer choice in which the first word either describes what one typically does with the second word, a noun, or is a synonym of the second word, a verb. Since none of the potential answer choices are pairs of synonyms, we will need to look for an answer choice in which the first word describes what one typically does with the second, a noun. While "type is to keyboard" might look like a potentially correct answer, one uses a keyboard to type—one does not "type a keyboard." So, "type is to keyboard" cannot be the correct answer. One does climb a mountain just like one bestows an award, however, so the correct answer is "climb is to mountain."
