Final answer:
The blank in the sentence can be correctly filled with 'fixed,' 'mended,' or 'repaired,' but 'repaired' would be the most technically appropriate option for a washing machine, although 'fixed' is also widely used.
Step-by-step explanation:
The sentence "He _____ my washing machine two days ago." can be completed with any of the three options provided, as they are all synonyms in this context. However, they do have slightly different connotations:
- Fixed often implies a general solution to a problem.
- Mended is less commonly used for mechanical or electrical repairs and is more often associated with repairing fabrics or materials.
- Repaired suggests a more technical or formal fix, particularly for machinery.
All options would make the sentence grammatically correct, but given that we are talking about a washing machine, which is a piece of machinery, the most appropriate choice might be:
He repaired my washing machine two days ago.
Nevertheless, fixed would also be suitable and commonly used in spoken language.
