"Intellectual" is defined as relating to reasoning and understanding, especially with regard to abstract and rational matters; thus "educated" is the best answer choice.

Coarse means rough in texture or rude and vulgar, so "vulgar" is the correct answer. For instance, swear words are often referred to as "coarse language" or "vulgar language."

"Mild" is an adjective that can mean gentle or moderate. So, "harsh" cannot be the correct answer, because "harsh" is an adjective that can mean severe, making it an antonym, not a synonym, of "mild." "Gentle," however, is an adjective that means mild and tender or moderate. So, because "gentle" is the answer choice closest in meaning to "mild," "gentle" is the correct answer.

"Timid" means shy, so "shy" is the correct answer. To help you, "bold" means brave and confident, and "audible" means able to be heard. (The root "aud" is often found in words that have to do with hearing, like "auditory" (having to do with sound and hearing) and "auditorium" (a large room in which concerts and performances are held).)

Someone who is "valiant" is very brave, so "brave" is the correct answer. To help you, "humorous" means funny, "shocked" means surprised, and "meek" and "timid" are both synonyms of shy.

“Meticulous” means careful or paying attention to detail, which is the same as if someone is “precise,” which means paying attention to detail. So, "precise" is the correct answer. None of the other answer choices are close in meaning to "meticulous": “uncoordinated” means not organized or clumsy; “synchronized” means in or on time with something; “severed” means cut off; and “disastrous” means unfortunate or terrible.

"Reliable" means able to be relied on or trustworthy, so the answer choice that is closest in meaning to "reliable" is "dependable," which means able to be depended on or trustworthy. "Irresponsible" is an opposite, or antonym, of "reliable," and means not acting responsibly or not able to be relied upon. None of the other answer choices are related in meaning to "reliable": "hearty" means substantial when referring to food and boisterous and cheerful when referring to people; "astounding" means amazing or shocking; and "interesting" means holding one's attention or fascinating.

To be compassionate is to be caring. "Kind" means caring and supportive, and thus is a close synonym to "compassionate."

Something “heroic” has the characteristics of a hero, and as such it is most similar to the word “brave.” To provide further help, someone who is “boastful” likes talking about him- or herself; and “beneficial” means helpful.
