The sentence should be corrected as follows: "The Olimpic athlete raced down the slopes because he hoped to win the gold medal."
The correct options are:
* by changing "though" to "because" since it is proving an explanation to the 1st part of the sentence.
* by changing "hopes" to "hoped" since the 1st part of the sentence is in the past tense.
The incorrect options are:
* by removing "down the slopes" since it adds details about the meaning of the sentence.
* by replacing "he" with "the athlete" since the latter is already mentioned in the sentence and can be replaced by personal pronoun "he".
* by replacing "the gold medal" with "it" since the latter is not mentioned before in the sentence. Therefore, it cannot be replaced by the personal pronoun "it".
i think its the first option
