"Irate" most nearly means furious, or extremely angry. "Perturbed" also implies a disturbed mental state, but the degree of intensity is not severe enough to be a synonym for "irate". "Measured" and "controlled" both imply a state of calmness that does not correspond with "irate." "Energized" means to be full of vitality or excitement, which has no relation to the word "irate."

"Elated" means to make someone very happy. "Thrilled," which means to cause someone to have a sudden feeling of excitement and pleasure, is the best synonym of "elated."

"Stationary" is an adjective that means "not moving," so we need to pick out another adjective that means "not moving." While "fast-moving" also has to do with movement, it means the opposite of "not moving," so it can't be the correct answer. "Motionless," on the other hand, means "not moving," so "motionless" is the correct answer.

“Final” is an adjective that can mean “coming at the end,” “reached as the outcome,” or “allowing no further doubt.” So, we need to pick out an answer choice that means something like “coming at the end” or “allowing no further doubt.” That means that “initial” cannot be the correct answer, because “initial” means “existing or occurring at the beginning,” making it an antonym, not a synonym, of “final.” “Last,” however, is a word that when used as an adjective means “coming after all others in time or order; final,” and because “last” is the answer choice closest in meaning to “final,” “last” is the correct answer.

“Prepared,” when used as an adjective, can mean “ready for something : in a suitable condition for some purpose or activity,” so we need to pick out an answer choice that means something like “in a suitable condition for some purpose or activity.” That means that “unready” cannot be the correct answer, because “unready” means “not prepared for a situation or activity,” making it an antonym, not a synonym, of “prepared.” “Ready,” however, is an adjective that means “in a suitable state for an activity, action, or situation; fully prepared,” and because “ready” is the answer choice closest in meaning to “prepared,” “ready” is the correct answer.
