Choose the option that best completes the gap(S).Tsadu always cautions that difficult jobs should be done _____?
Answer Details
The option that best completes the sentence is "step by step".
"Step by step" means to do something gradually, taking one step at a time, or proceeding in a careful and deliberate manner. In this sentence, Tsadu is cautioning that difficult jobs should be approached carefully and systematically, one step at a time. The other options do not convey the same meaning and are not suitable to complete the sentence in the given context. "Step from step" and "steps after steps" do not make sense in English, and "steps by steps" is not the correct grammatical structure.
