Choose the pronoun that replaces the underlined word correctly.

The runners were thrilled when Speedy Shoes offered the runners each a free pair of training shoes.

they
them
their
there

Assuming that the underlined word or words would be "the runners", the answer would be "them".

Explanation:

Them makes the most sense when it's replaced by the underlined word.

The runners were thrilled when Speedy Shoes offered them each a free pair of training shoes.

With they, their, and there, replacing the phrase with these words would bake the sentence grammatically incorrect if written and awkward if said out loud.

The best answer would be them.

1. okay which is underlined? and if it is THE that needs changing than it would be "them runners were thrilled when Speed Shoes offered the runners each a free pair of training shoes"

2. if it is not THE that needs changed then it would be this "The runners were thrilled when Speedy Shoes offered each of them a free pair of training shoes"

If you did not use them on each it would not be correct it would  sound awkward and be incorrect for example "there runner's were thrilled when Speedy Shoes offered each a pair of training shoes" It does not sound right does it?

They do not fit this sentence correctly there means the opposite of here “there at that place.” Their means “belongs to them.” They're is a contraction of “they are” or “they were.” So the only option is them

Thus, answer is them

postive, comparative, superlative - good, better, best

recall how we defined nouns as words capable of having plurals and possessive endings. adjectives (and their first cousin, the adverb) also have a feature that distinguishes them. they come in three states. first, the raw adjective—in its positive state—merely describes the noun modified; it doesn’t care about how this particular person or thing stacks up against other members of the same noun class
