Here, the only way to choose the correct answer is to find the one that most directly matches the key expression “he must believe that nobody else actually exists.” While many of the options deal with “self-centeredness,” only “solipsist” means “someone who believes that only oneself can be known.” The word comes from the combination of the Latin “solus,” meaning “alone” and “ipse,” an intensifying pronoun meaning “him/her/itself.” The first can be found in words like “solitary” and “solitude.” The latter can be found in odd English words like “ipseity,” meaning “selfhood,” as well as the Latin expression used in legal parlance, “res ipsa loquitur,” meaning, “The thing (event, data) speaks for itself.”

The explicit statement in the sentence refers to the production of milk. Therefore, the option “lactation” is the best answer, for this is the word for the secretion of milk from a mammalian mother to its child. The “lact-” prefix comes from the Latin for milk and is found in English words like “lactose,” a type of sugar found in milks and “lactic acid,” which is found in sour milk but also in the body after exercise, causing soreness.

The key expression is “eat nearly any type of food.” Note that this does not say that Ken eats large quantities of food. Therefore, any of the options that imply gluttony (and so forth) are not acceptable. The sentence is a bit playful, using a word as an affectionate title. Based on the context, we can tell that the title must mean something like “eats everything.” To this end, “omnivore” fits well. The word literally means “eating all things.” The “omni-” prefix (meaning “all”) is found in many word like “omniscience” and “omnipotent.” The “-vore” comes from the Latin for “to swallow,” though it is used in words like “voracious” (desiring much food) and the other “-vore” words like “herbivore” and “carnivore.”

The key thing to note in this sentence is that the vegetarians are described as eating more than plant products. The implication is that they cannot be called properly “animals eating only plant products.” Such animals are “herbivores,” a word constructed from the parts “herb-”, meaning “grass,” and “-vore,” literally meaning “to swallow.” The prefix is found in words like “herbicide” (something that kills grasses) and “herbal.” The latter is found in words like “voracious” (desiring much food) and the other “-vore” words like “omnivore” and “carnivore.”

Since the sentence is very vague regarding exactly what the crown matched on the King, the word to be chosen must likewise be vague. Although it is a bit old-fashioned, the word “raiment” means “clothing.” It is often used literarily, so the application to a king is perhaps somewhat understandable.

When someone does not charge an official fee, such a person might be given a small gift in return for his or her services. Such a gift is called an “honorarium”—an honorary payment that is not considered as an official reimbursement as much as a gift.

The general sense of the sentence is that each of the parts of the complex engine is just as intricate as the overall engine. The word “component” means “a part,” particularly “a part of a machine.” The word comes from the Latin meaning “put together.” The “together” is derived from the “com-” prefix which you likely know means “with.” The second half of the word is derived from the Latin for “to put or place” and is related to many other English words such as “position,” “postpone,” and “proponent.”

The implication of the sentence is that while the law had been passed, it was not put into official force because it needed explanation to the people. Although several options might seem appropriate, the best word is “promulgation.” In a broad sense, the word means “the act of making something known to many.” It has the further restricted sense of making a law known to many. This fits well with this sentence’s needs.

For this sentence, there are two possible ways of finding the answer. If you know the word “thurible,” you will know that such devices are used for the burning of incense. This immediately provides the answer; however, if you do not know that vocabulary item, it is likely that you know that the burning of incense gives off “vapors” in a smoky form.

The key word is “dwindled,” which describes the pile as shrinking. When something shrinks in size, it is said to “diminish” or to undergo “diminution.” These words are likewise related to English words having the prefix “mini” such as “miniature,” “minute,” and “minimal.”
