Excuse me, do I have problems with grammar and usage of this English question?

Hello, there are fifty students in our class some are from the usa, and __are from china.

a) another

b) the other

c) others

d) other

The answer is indeed c, not b. When other has the definite article the as a modifier, it is (specifically), and the other is used as a noun (singular), indicating that 49 of the 50 people in the class are from the United States and 1 is from China. But the part in the sentence indicates that (some) is not (the vast majority), and the other is that the verb after the space is are, not is, which means that the space is a table (plural) and not (singular).

The other in answer B is a table (argumentative stupid singular), specifically referring to (the other), so the correct answer is the other of c, and the other in this case is used as a pronoun. The assessment of sentences is the usage of some and other. When some is (pronoun), it is translated as (some [people and things]) using plural predicate verbs, while other as (pronoun), there is a distinction between singular and plural, other is singular and others is plural; And as the other, it is singular, not plural, and the plural companion form is the others.

Hello, her parents hoped she can marry into the nobility and enter the highest ranksHere ranks is the noun plural.

Form. rank can be used as a countable noun or as an uncountable noun.

Meaning: countable noun: status (in an institution or association); Class; Military rank.

Uncountable noun: high social status, such as a person of rank and breeding

When rank is used as a countable noun, it can be used to indicate the status (of social class), and there are many kinds of social classes, that is, the social status of different industries, different bloodlines, different families, and so on. So the rank is used here, and the highest ranks is used as a modifier, which should mean that there can be multiple top positions across different industries, different bloodlines, and different families. For example, a rich second generation, a leading enterprise in a certain industry, or a leading scientific and technological position, etc., not just a status.

In ancient times, the highest status was the emperor and queen, but in modern society, every industry has a leader, every place has a more prominent family, or a certain surname is noble. Therefore, I personally think that this sentence is that parents want their daughters to marry into a prominent position (a status), or the CEO of a company (a status), or maybe a hegemon (a status) and so on.

Personally, I understand that the highest here does not refer to a specific one, if it is specifically referred to, then in feudal society, for women, it should be to become a queen.

Therefore, the corresponding rank (class) does not refer to a specific class, but refers to a relatively high level, so it is necessary to use plural. For example, for Chinese feudal society, the second grade or above is a big man and the like.

rank is a third-person plural, which is customarily used to refer to a higher status or class or military rank, and has the meaning of "belonging".

Because the prefix has the highest superlative, followed by the plural noun.

A predicate is a sentence component, and the predicate verb dan spine is a central word.

Earlier, it is important to know that English sentences must have a subject and a predicate, and secondly, predicates are not necessarily verbs, such as play, cry, etc., and the form of the verb be. According to your understanding, it is also possible. i am reading a book.

The predicate verb is am reading
