What is the correct contraction for "will not"?

"The package lay on the table."

"Drop" does not fit the sentence because it implies that the package fell onto the table, which may not be the intended meaning.

"Laid" is the past tense form of the verb "lay," but it requires an auxiliary verb (such as "has" or "had") to form the perfect tenses. Without an auxiliary verb, "laid" is not appropriate in this context.

"Lay" is the correct simple past tense form of the verb "lie," which means to be in a horizontal or resting position.

"Layed" is an incorrect spelling and should be avoided.

The phrase "Because I" is not incorrect in itself, but it is not used correctly in the given sentence. It is used as a fragment and does not connect properly with the rest of the sentence. It lacks a main clause to complete the thought.

"Ain't" is a colloquial contraction used to represent "am not," "are not," or "is not." However, in formal or standard written English, "ain't" is considered nonstandard and should be avoided. In this context, a more appropriate word would be "isn't" or "is not."

The correct form to use in this context is "its cover" without the apostrophe.

Therefore, the corrected sentence would be: "You can't tell a book by its cover" is an old adage.

The possessive pronoun "its" is used to indicate that the cover belongs to the book. It does not require an apostrophe in this case.

The options A. "a book," C. "can't," and D. "an old" are used correctly in the sentence. It is only the incorrect use of "it's cover" that makes the sentence grammatically incorrect.
