The quote "more like a king, composed, farther and farther on" has a very important meaning. It is saying that you should, rather than be shy, or to not have pride in one's self, instead compose yourself "more like a king". It is saying that you should be proud, and that you should carry yourself in a way that makes others admire you, because you have pride in yourself.
Let us dissect each sentence to tell which of these does not follow the rules for subject-verb agreement.
A.) The subject is 'each of the students' while the verb is 'is'. More particularly, the verb refers to 'each' which is singular. So, this is correct.
B.) The subject is 'student' while the verb is 'were'. The word 'were' is the paste tense of are which is used for a plural subject. But since student is singular, then the verb should have been 'was'. So, this is incorrect.
C.) The subject is 'my dog and my cat' which pertains to two nouns, thus it is plural. It agrees with its plural verb 'are'.
D.) The subject is 'Tom' while the verb is 'does'. Both are intended for singular use. So, this is correct.
Therefore, the answer to this is letter B.
C uses the most positive form of an adverb
Answer is A. Nora realizes that Helmer will completely disapprove of her having borrowed money, so she has to continue to keep it a secret from him.
In the excerpt from Act 1, Nora agrees with Helmer's ideas about borrowing and debt. By saying "As you please, Torvald." she pretends not to care about such problem, as if she has never borrowed money from anyone. In fact, regarding Helmer's hypothetical death situation, she gives more importance to her loosing him than to the hypothetical debt. In this way, Nora successfully draws his attention away from his worry.
