"Terse" means brief or concise, so "concise" is the correct answer. "Verbose" is an antonym of "terse"; it means very long and wordy. None of the other answer choices are related in meaning to "terse": "parched" means very dry; "shallow" means not very deep; and "passionate" means having a strong feeling or conviction.

“Obscure” means hidden or esoteric, so "hidden" is the correct answer. Something that is “obvious” is easy to know and understand; “coherent” means able to be understood; “abrupt” means happening quickly and suddenly without any forewarning; and “acceptable” means good enough.

Perhaps you have heard of "ductility" in your science class. This is a property of metal that describes its ability to be made into a wire. For something to be "ductile" (and hence formed into a wire), it must be flexible. Otherwise, it would break. Do not choose "ventilated" (as though the word "ductile" was related to "air ducts"). Likewise, don't choose "wired!" Something that is ductile can be made into a wire; however, it certainly is not itself "wired."

The word "radiant" comes from Latin roots that mean to send out rays. Think of X-rays. Such technology is so named precisely because these devices use waves or "rays" to detect bone (and other) structures in your body. There can be "rays of sun," meaning the sunlight itself, shining. Thus, when we say that something is "radiant," we mean that it is shining. This word can be used metaphorically meaning joyful, as we say something like, "He was radiant when his mother told him that he would have his favorite dessert that that night."

For this word, be careful not to be fooled! There are a number of options that are meant to fool you into choosing a word that is only close but not exact. When things are "identical," they are exactly the same. Thus, it is not fair to say that they are merely similar, akin, or alike. All of those options merely mean that the things in question are nearly the same but not quite. Thus, the best option is "duplicate."  duplicate is a double of something else. It is an exact copy. Thus, this option is far better than the other ones offered!
