determiners - "every" vs "each"?

Consider:

The ten lucky winners will ................. receive $1,000.

A) every

B) each

The answer in the book is each. As far as I know, every and each are used before singular nouns. I cannot understand the grammatical structure of the sentence. The only thing that I can guess is that each, as oppose to every, is also pronoun but, I don't know how this would help!

Note 1: The book preview option is not available although the book can be found on the google books!

Note 2: I know each has different connotation from every; the former has one-by-one connotation, the latter has a collective connotation; the problem is about the grammar.

Answer

The ten lucky winners will......receive $1,000.

Each and every are often similar in meaning. The only difference is between their usage as follows:

First, you use each when there are two or more things in a group, whereas you use every when there are three or more things in a group.

Second, the usage of each gives stress to individual things in the group, whereas every refers to things in the group as a whole. For example, every student passed the test = All the students passed the test.

Third, each is used as a determinor, pronoun, or adverb, but every is only used as a determiner.

Each and every are only interchangeable to convey the same meaning when there are three or more things in a group, and we use them as a determiner, without considering the stress they indicate.

Look at the following sentences to find how every is used as a determiner, and each is used as a determiner, pronoun, and adverb:

Every lucky winner will receive $1,000. (determiner)

Every one of the ten lucky winners will receive $1,000.(determiner)

Each lucky winner will receive $1,000. (determiner)

Each of the ten lucky winners will receive $1000.(pronoun)

The ten lucky winners will each receive $1,000. (pronoun)

The ten lucky winners will receive $1,000 each. (adverb).

As 'each' as a pronoun fits in the blank space of the sentence presented by the OP, you cannot use the determiner every here.
