"Flex" means bend and the suffix "-ible" means able to be, so "flexible" means able to bend or be bent easily, and "bendable" is the correct answer. “Rigid” is the opposite of “flexible"; it means strong, sturdy, and unable to have its shape changed easily; “stern” means very strict; “stable” means steady or unchanging; and "rough" means having a coarse and grating texture.

The suffix -spec means look so to "inspect" something is to look at it. "Love" is an emotion, and is not related on word level to "inspect." "Smile" and "laugh" are both things that you might do while inspecting something, but they're not actually related to the word in anything but an incidental way.

The prefix in- means not and the suffix -able means able to be. So, "incurable" means unable to be cured. This is closest in meaning to "deadly." Additionally, "probable" means likely; "edible" means able to be eaten; "envious" means jealous, wanting something that someone else has; "brainy" means clever. 

The suffix -ator means person who does. As in "protestor," which means person who protests or "demonstrator," which means a person who demonstrates against. These two words are synonyms. So, an "agitator" is someone who agitates. To "agitate" means to disturb, to cause trouble. The correct answer is therefore "troublemaker." Additionally, a "moderator" is someone who oversees a debate; a "guardian" is a protector, someone who protects.

The prefix a- means not and the suffix -theist means God. So, an "atheist" is someone who does not believe in God. This is closest in meaning to "nonbeliever." Additionally, a "deity" is a God; an "agnostic" is someone who is unsure as to whether or not God exists; a "fanatic" is someone who follows something passionately; an "editor" is a person who edits and makes decisions regarding the content of things like newspapers and magazines.

The suffix -ify means to make into. So, "purify" means to make pure. This is closest in meaning to "clean." Additionally, "revere" means deeply respect and admire; "improve" means make better; "detract" means take away from. 

The suffix -less means without. As in, "hopeless" which means without hope. So, "worthless" means without worth. Which is closest in definition to "unimportant." Other synonyms include "insignificant" and "useless." Additionally, "inexpensive" means not expensive; "homely" means unattractive, plain in appearance; "abrupt" means happening suddenly and unexpectedly; "materialistic" means overly worried about image, money and looks. Based on these words what do you think the prefixes un- and in- mean?

Additionally, "commence" means begin; "beam" means smile widely; "harass" means annoy, irritate, pester, bother; "radiate" means emit, give off (energy).
