Final answer:
The two incorrect words in the student's sentence are 'to' which should be 'two', and 'your' which should be 'you're'. Correcting these homophones is essential for the clarity of the sentence.
Step-by-step explanation:
The sentence provided by the student contains two errors. The incorrect words are 'to' which should be 'two' indicating the number of weeks, and 'your' which should be 'you're', the contraction for 'you are'. These errors are common homophones, words that sound the same but have different meanings and spellings. It is essential to use the correct form to convey the intended meaning in written English.
Correct sentence: 'I've only known Wanda for two weeks, but I can already see why you're such good friends.'
