The word “ardent” is related to “ardor,” which means passion or zeal. Both of these terms come from that Latin verb meaning to be on fire. In a sense, you can think of them as expressing “being on fire” emotionally for some project, goal, or aim. When someone is called, for example, “an ardent supporter,” he or she is a strong and zealous supporter of that cause. Likewise, when one “ardently discusses a topic,” he or she does so with great enthusiasm and vigor.

When someone is “overwrought,” that person is excited or anxious. While that might cause someone to be jittery or even annoying, the best option among those given is the mere direct definition, “anxious.” The word would be used in a sentence like, “Having arrived at the long-feared day, Jonathan was so overwrought that he could not even sleep because of his agitated nerves.”

The word “tempestuous” is related to the word “tempest,” which is a strong wind storm. When applied to a human person, it implies that the person has a very strong emotional disposition. Someone could say, “John had an extremely tempestuous attitude, often screaming at his subordinates and always arguing with someone.”

The word “vacant” is related to the word “vacuum,” meaning “empty space.” Sometimes, you will hear an expression like “a vacant lot” to describe a piece of land that has nothing built on it (and perhaps is abandoned and unused). The word can also be applied to the expression that a person has. When someone shows a “vacant expression,” he or she has a “blank stare.” Often this implies that there is no emotion expressed at all.

"Jubilant" is an adjective defined as "feeling or expressing great happiness and triumph." While all of the answer choices describe moods or emotions, only "gleeful," an adjective that means "exuberantly or triumphantly joyful," is a synonym of "jubilant," so "gleeful" is the correct answer.

“Morose” means in a bad mood and miserable, so "sulky" is the correct answer. “Lofty” means high-up or proud; “timid” means shy and quiet; “tepid” means lukewarm when describing temperature and unenthusiastic when describing responses; and "macabre" means morbid and grotesque.

"Queasy" means uneasy or uncomfortable. "Grotesque" means ugly or misshapen. "Reserved" means quietly unsociable or restrained. "Mundane" means boring or day-to-day. "Weary" means tired or exhausted. 

“Jovial” means jolly, friendly and "cheerful." As for the other answer choices, “uncomfortable” means slightly painful or just removing or lacking all comfort; “hollow” means containing empty space on the inside; "nuanced" means full of subtle details; and “deft” means skillful.

When something is dilapidated, it is run down. This does not mean that it is totally destroyed. Nevertheless, a dilapidated piece of property is in poor shape.  The word comes from roots that literally mean with stones fallen down. While such a piece of property might be inexpensive or ugly, this is not what "dilapidated" means.  "To be dilapidated" is to be in a state of disrepair or ruin. Thus, the best option is "battered." While this can be used to describe someone who has been physically injured, it also can be used to describe something that has been worn down by use or over-exposure to poor conditions. Thus, someone can have a "battered old car."

For this question, you have to be very careful to match the synonym most closely. The options provided all are related to the word "irate." Note that "irate" means the state of being extremely angry. Thus, "enraged" is the best option among those provided for "irate."  All of the other ones are too weak for so strong an emotion.
