When I realised I had dropped my gloves, I decided to ...... my steps.*retraceregressresumereturn

To fill in the blank in the sentence "When I realised I had dropped my gloves, I decided to ...... my steps," the correct choice is "retrace."

Explanation:

1. Correct Verb Choice: The word "retrace" means to go back over a route previously followed, which fits perfectly in the context of recovering lost items.
2. Other Options:
   • "regress" typically refers to returning to a previous state or condition and does not convey the action of going back over one's steps.
   • "resumer" is not a correct word in standard English usage.
   • "return" could also fit but is less specific than "retrace" regarding the action of following the same path.

Final Answer

Thus, the sentence should read: "When I realised I had dropped my gloves, I decided to retrace my steps."
