To solve this problem it is necessary to consider the meaning of the root of the word "scribe." The root word -scrib- means write, so a "scribe" is a writer. To "inscribe" is to write in for example. 

To solve this synonym you have to examine the roots in the word "incredible." -cred- means believe and in- means not. So the word "incredible" means not believable, which is the same as "unbelievable." Notice here how the prefixes in- and un- both function the same way, they take the original meaning of the word and negate it causing it to mean the opposite. So "unwelcoming" means not welcoming. 

The roots -vers- and -vert- mean turn. As in, "revert" which means turn back, return to a previous state. "Versatile" means adaptable, able to change to suit different environments or situations.

Additionally, "viable" means workable, capable of being accomplished; "portable" means able to be moved, able to be carried; "incapable" means not capable, not able to do something; "incomprehensible" means not able to be understood. Based on these words what do you think the suffixes -able and -ible mean?

The root -mal- means bad. It is a very common prefix and appears in words like "malevolent" which means bad natured and "malicious" which means cruel. So, "dismal" must mean something bad. All of these answer choices describe a state of happiness, except "depressing" which means very sad. "Dismal" means depressing, gloomy, dark.

The roots -vey- and -vect- mean carry, move. So, to "convey" means to move from one place to another. This is identical in meaning to "transport." Additionally, "whine" means complain about; "stare" means look at intensely; "tumble" means trip, fall over; "mumble" means whisper, talk quietly, talk in a way that is hard to understand.

Additionally, "momentous" means massive, of great importance; "frustrated" means annoyed, irritated; "alleviated" means (of pain) made better, soothed; "circumstantial" means (of evidence) indirect, only partially relevant or applicable.

The prefix vis- means see, sight and the suffix -ible means able to be. So, "visible" means able to be seen. This is closest in meaning to "clear." Additionally, "dense" means thick; "acute" can mean sharp, clever or severe, intense or it can describe an angle in mathematics that is less than ninety-degrees; "obtuse" can mean stupid, not clever or it can describe an angle in mathematics that is more than ninety-degrees, but less than one-hundred-and-eighty-degrees; "parallel" means in line with, a line that runs alongside another line.
