Question

which sentence is correct? hint: \all ready\ means completely ready; \already\ means previously started or done. the experiment is already for the scientist to complete. the scientist already completed the experiment. the scientist is already to complete the experiment.

Explanation:

• For the first sentence “The experiment is already for the scientist to complete.”, the usage of “already” is incorrect. It should be “all ready” (meaning completely ready) in this context as it describes the state of being ready for an action.
• For the second sentence “The scientist already completed the experiment.”, “already” is used correctly. It indicates that the action of completing the experiment was done before the present time (fits the meaning of “previously started or done” as per the hint).
• For the third sentence “The scientist is already to complete the experiment.”, the usage of “already” is wrong. It should be “all ready” to show the state of being ready to perform the action of completing the experiment.

Answer:

The scientist already completed the experiment.
