Answer:

Luminosity classes are labeled with Roman numerals from I to V: I are supergiant stars, II are bright giants, III are ordinary giants, IV are subgiants, and V are ordinary main sequence stars. The complete spectral classification for a star is then given by specifying both the spectral class and the luminosity class.

Which sentence uses a verb that agrees with its compound subject? A. Either calculators or an adding machine make an accountant'
Sladkaya [172]
I believe B would be the answer, as the subject closest to the verb (rolls) corresponds to the verb (when there is an "or" or "nor" in a sentence, the verb should correspond to the subject closest to it). For A, "adding machine" should correspond to "make," but it doesn't. For C, the subject is plural (team members and the coach), but the verb is singular; the case is the same for D.

Dominik [7]

In this excerpt the narrator is complaining about the way achievement test are and how up to that they measure someone’s knowledge. He uses the word bland to describe the right answer of this kind of tests which it means „lacking a strong or particular flavor; not interesting”, in this context can be used describing it as non-sense or not obvious answers. He also complains about how bad he is in this because he cannot find the logic in the answers. With this explained, we can infer that the right answer is D Tan believes that achievement tests give inflated measurements of language ability, because he kind of argues that the answers are not "valid" to measure it.

Nadya [2.5K]

Answer: B, Praised

Explanation:

I assume you meant to italizice commended.

We need to look at the context of the sentence to get the answer- scolded is an ayntonym to commended, it means you got in trouble.

And if Donnie was <em>volunteering</em>, meaning working for a non-profit organization, then he couldn't have gotten paid or promoted.
