Question

what is the correct meaning of the word method?
my brother came up with an unusual method for cleaning his room.
a purpose for working
a way of doing something
a new idea
a useful tool

Explanation:

To determine the meaning of "method" in the sentence "My brother came up with an unusual method for cleaning his room", we analyze the context. A "method" here refers to a way of performing the action (cleaning the room). "A purpose for working" is incorrect as it refers to intent, not a way. "A new idea" is more about a concept, not a way of doing. "A useful tool" refers to an object, not a way. So "a way of doing something" fits.

Answer:

B. a way of doing something (assuming the options are labeled with letters, if not, the option text "a way of doing something")
