This is a phrase, not a sentence. It lacks any sort of verb or predicate to qualify it as a sentence.
It would be the house of the Secretaries of State.
Yes, it is correct if you are speaking about the boss of more than one secretary (the plural possessive form.) If you were speaking of the boss of one secretary the proper spelling would be secretary's. The plural of secretary is secretaries. The possessive of secretary is secretary's. The plural possessive of secretary is secretaries' (I have heard that secretaries's is technically correct, but I find it cumbersome myself.) In general the possessive form of words ending in S is that word with an apostrophe on the end. !
No, this is not a correct sentence. The correct one is, there is another beauty in the family.
Only one sentence is correct. The correct sentence would be "He saw me going there".
The latter one is the correct sentence by structure. The correct one is, he contributed in organizing the program.
Yes. That is a correct sentence, or at least a correctly formed sentence*. But there is no content that can be judged as right or wrong. (*It is an interrogative sentence, one that asks a question.)
The sentence is correct exactly the way it is: "One of these disks is for you and Adam." "Is" is the correct form of the verb "to be" in this sentence, because its subject is "one," which takes the singular form of the verb. Note that if the sentence had started with "these disks," that would require a plural verb, and the correct form would be "These disks are for you and Adam."
"It is one of the biggest cities" is correct.
The sentence has one error, the word route means 'the way to get from one place to another', the correct word for the sentence is root meaning 'origin, source, or base'. The correct sentence should read:You tried to get to the root of the problem.
They are not in one
It depends on the meaning.If who refers to them, the sentence is He is one of them who are guilty.If who refers to he, then the sentence is He is one of them who is guilty.
No this is incorrect grammar. To make the sentence grammatically correct you should say: One of my cousins came yesterday.
