Which sentence uses the underlined
vocabulary word incorrectly?
A. My brother annoys me when he is sagacious and
starts stuttering all of his words.
B. He squealed in ecstasy when he won the jackpot.
C. With disapprobation on her face, she accepted
my sloppy, handwritten paper.

The answer would be Option A.

Explanation:

This is because the meaning of "sagacious" in Option A means to be wise   and /or good judgement. That is with sharp contrast with the rest of Option A's sentence. This is because good judgement is an antonym with "annoys me." And nobody with good judgement is annoying, at least in a personal stance.

Looking at the other options, Option B would be used correctly as "ecstasy" means happy and/or excited. And this fits into the sentence just fine, because he won a jackpot! Who wouldn't be excited?

Option C would also be used correctly as "disapprobation" means to dislike. And this fits into the sentence, like Option B. This is because the handwriting is "sloppy", meaning that it's most likely rushed and lower quality.

This leaves only Option A, as the only sentence to be used in incorrect context.  

each year on this day, i make it a point to listen to dr. martin luther king jr.’s great “i have a dream” speech. it’s electrifying every single time.

the content of dr. king’s speech, his inspiring presence, and the moment in history all came together to make the iconic “i have a dream” speech the defining moment of the american civil rights movement. but there are several other reasons why this speech, delivered over 50 years ago, remains an example of one of the best speeches in american history.

since part of my job is to people become better presenters, i’ve noticed several techniques that we can all learn from and be inspired by in this magnificent speech.

it’s anchored in a powerful related location

in most cases, you can’t handpick the spot to give a presentation, as mlk did for supreme symbolic effect when he stood on the steps of the lincoln memorial and echoed the opening words of the gettysburg address (“five score years ago . . ). but you absolutely can amplify your message by adapting it to your setting and location.
