Fill in the blank with the correct determiner: ____ shoes are really expensive Choose the correct reported speech: He said, "I am going to the market".

Here are the answers to your questions:

16. C) The correct determiner is These. "Shoes" is a plural noun, and "These" is used to refer to plural items that are typically in the immediate context or being discussed.
17. B) The correct reported speech is "He said that he was going to the market." When converting direct speech to reported speech, the pronoun "I" changes to "he", and the present continuous tense "am going" changes to the past continuous tense "was going" because the reporting verb "said" is in the past tense.
