Which one is correct grammatically?

"Thanks to all" is correct in both sentences.\nI would write "Thanks to all of you for answering."\nIt seems more personal to me, even though it not as succinct.

Actually, you do.\n\n"Is", since it is a verb, requires capitalization.\n\nRule Number 8 at grammarbook.com:\n"Capitalize short verb forms such as Is, Are, and Be."

TU would be the correct one, because you are talking about one table(mesa). If the sentences was mesas, then you would use TUS.\nSINGULAR=TU  PLURAL=TUS

The first and third are correct. The first is in future tense. Still acceptable depending on context of the sentence.

It's B; I'm very certain.\n\n"A" has a subject, verb, and a direct object.\n"C" has a subject, verb, and a prepositional phrase.\n\nBut "B" is the one that has a subject complement, "better," which describes the subject, "I."

Either with a comma or without a comma; either is correct.

Well...it actually is debatable, but I'd go with "was" to be on the safe side...\n\nWith either/or (neither/nor) things that contain subjects that take different verb forms, there is no definitive agreement on which form the verb should take.\n\nA majority, however, says that you should follow the subject that is closest to the verb, in this case " I ", so, since:\n\nI WAS asking for refills --> Neither you nor I was asking for refills.\n\nA minority say that the verb should always be singular in these cases, and an even smaller minority say that either verb form is acceptable.\n\nSo your best bet to avoid the ire of an anal-retentive English teacher (or professor, editor, yourself, etc.) is to go with the "closest to the verb" rule, in this case WAS.

No, it isn't correct.  Correct usage would be, "Has he got the money?" or "Did he receive the money?" or "Has he received the money?"

There is not any instance in which (d) could be the correct answer because (d) is grammatically incorrect. The "many things" must be referred to in a plural noun to make the response balance. You wouldn't say "What are it?" because you are referring to more than one thing. The (c) answer, "What are they? clearly asks of all the things he has in is box, What things are in the box?

Grammar- it's grammar.\nYou know, with two "a"s.\nAlso, in this case, use "their".\n"There" describes a place.

1. There are a lot of books. (example on cooking here)\n\n2. There is a lot of books.\n\nWhen the subject (Books) is plural the verb always changes. In this case its third person plural form of the verb "to be". That is why, you have to use are instead of is.\n\nIf you have to say the same sentence with singular (Book) then its:-\n\nThere is a book (on cooking here).\n\nConjugation of the verb to be:-\nSingular\nFirst Person:- I am\nSecond Person:- You are\nThird Person:- It is\n------------\nPlural\n1st Person:- We are\n2nd Person:- They are\n3rd Person:- They are\n\nHope this helps!

You can use either when adding a qualifying clause afterwards.\n\n"I like the cat which is red"  "I like the cat that is red" both work. \n\nThat sounds a little more casual/natural.  Which sounds a bit more high brow formal.  \n\nThat can also double as a pronoun.  Avoid using the word "that" twice in a row however.  "That which is wrong"  vs "That that is wrong."

Yes, that is correct... however it's spelled 'grammar'.. not 'grammer' :)

Neither is correct.  When using this phrase, you should say "the reason is..." and then state the reason.  using because or that is is unnecessary.
