Decide if the following is an opinion.If you flap your arms fast enough, you can fly.

A. opinion

B. not an opinion

Answers

Answer:

The correct answer is: not an opinion.

Explanation:

An opinion is a thought or belief about something that is ambigious, meaning that one can either support of reject the idea.

However, it is a fact that no matter how fast a human flaps his arms, they will never be able to fly.

When a sentence is factual, one cannot chose to agree or disagree with it. Therefore, this phrase is not an opinion, but a wrong statement.

Not an opinion. Just wrong.

Select the appropriate word to complete the following sentence. The secretarial tasks are divided _______ several people.a. through
b. between
c. of
d. among

Answers

The word missing to make the sentence logical is a preposition, which is contained in option d. The idea of the sentence implies collaborative work. When a task is performed by a pair of individuals, the right preposition is between; whereas when referring to a group of individuals, it is necessary to use among. The hint to be able to select the right answer is "several people".

The right answer for the question that is being asked and shown above is that: "d. among." The secretarial tasks are divided among several people. That is the correct word that is to be used.

Daphne owns a night club and frequently entertains large crowds. She feels very comfortable on stage and loves to make people laugh. Justin can?t bear even the thought of speaking to a large group of people. He gets butterflies in his stomach and shakes so badly he can hardly stand, and once even lost his job because he refused to give a presentation to the board of directors. In order to achieve the level of confidence that Daphne seems to have achieved, Justin could start by doing all of the following except:a.
gain experience by practicing speaking in front of others often, starting with close friends and family, then attempting larger groups
b.
imagine himself confidently delivering flawless performances, and the audience cheering and enjoying themselves
c.
write and rehearse stand-up comedy routines and research night club audiences and performers to prepare for an audition with Daphne
d.
make an effort to think positively about his abilities and look for elements of public speaking that he personally enjoys

Answers

The answer is C: write and rehearse stand-up comedy routines and research night club audiences and performers to prepare for an audition with Daphne.

Public speaking is an activity that involves confidence and, like any other activity, it can be perfected. Although some may have certain apparent innate skills conducive to public speaking, it, nonetheless, can be an acquired, learned, and perfected skill. As such, all of the options above would be conducive to a betterment of public speaking and gaining confidence in front of a crowd (even option b, where imagination is solicited, since imagining oneself succeeding at something can improve one´s own self-esteem making it easier to deliver). Answer C is not an option since it is only related to preparing and rehearsing a routine for an audition, so it does not meet the criteria above.

C, why would that help anything?!
