"Jovial" is an adjective that means "cheerful and friendly," so we need to pick out an answer choice that means something like "cheerful" or "friendly." While both "excited" and "affable" might look like potentially correct answers, "excited" doesn't mean "cheerful and friendly," so it can't be the correct answer. "Affable," however, means "friendly, good-natured, or easy to talk to." Because "affable" is the answer choice closest in meaning to "jovial," "affable" is the correct answer.

"Taciturn" is an adjective that refers to people and means " reserved or uncommunicative in speech; saying little." So, we need to pick out an answer choice that means something like "saying little." "Loquacious" might look like a potentially correct answer because it has to do with speech; one can recognize this by noticing the prefix "loq-", which is a root meaning "talk." However, "loquacious" means "tending to talk a great deal; talkative," so it is actually an antonym of "taciturn" and cannot be the correct answer. "Reserved," however, when used as an adjective, can mean either "slow to reveal emotion or opinions" or "kept specially for a particular purpose or person." Because the first meaning of "reserved" is synonymous with "taciturn," "reserved" is the correct answer.

"Illustrious" is an adjective that means "well known, respected, and admired for past achievements." So, we need to pick out an answer choice that means something like "well known," "respected," or "admired." Neither "forgettable" nor "substandard" can be the correct answer, because each word has a meaning that is nearly the opposite of "illustrious." "Preeminent," however, is an adjective that means "surpassing all others; very distinguished in some way," and because it is the answer choice that is closest in meaning to "illustrious," "preeminent" is the correct answer.
