Explanations:Quantifiers are words that indicate the quantity of a noun. They are used to modify nouns and provide information about the amount or number of something. In English, there are several quantifiers, including "many," "much," "few," "little," "some," "any," and "a lot of." The choice of quantifier depends on whether the noun is countable or uncountable.
Countable nouns are those that can be counted individually, such as "people," "books," "apples," and "cars." Uncountable nouns, on the other hand, cannot be counted individually and are often abstract or mass nouns, such as "water," "information," "advice," and "money."
When using quantifiers with countable nouns, "many" and "few" are appropriate. "Many" is used to indicate a large number, while "few" indicates a small number. For example, "There are many people at the airport" or "There are few people at the airport."
When using quantifiers with uncountable nouns, "much" and "little" are appropriate. "Much" is used to indicate a large amount, while "little" indicates a small amount. For example, "There is much water in the lake" or "There is little water in the lake."
The quantifier "so" is used with adjectives and adverbs to emphasize the degree of something. For example, "It is so cold today" or "She runs so fast." However, when "so" is used with nouns, it must be followed by "many" for countable nouns and "much" for uncountable nouns. For example, "There are so many people at the airport" or "There is so much water in the lake."
In the given sentence, "There were ..... people at the airport (that) we couldn't see my cousin," the noun "people" is a countable noun. Therefore, the appropriate quantifier to use is "so many," which emphasizes the large number of people at the airport. The correct sentence would be "There were so many people at the airport that we couldn't see my cousin."
It is important to note that "such" is used with singular countable nouns or uncountable nouns, not with plural countable nouns. For example, "It was such a beautiful day" or "It was such information." "So much" is used with uncountable nouns, not with countable nouns. For example, "There is so much water in the lake." "Such a" is used with singular countable nouns, not with plural countable nouns. For example, "It was such a beautiful day."
Understanding the correct usage of quantifiers is crucial for clear and accurate communication in English. It helps to convey the intended meaning and avoid confusion.
