Question 23
Select the most appropriate options to fill in the blanks.
The scientist worked tirelessly _______ the new invention, presenting it _______ the conference, and receiving praise _______ her peers.
Solution
Here, the first blank should appropriately link the verb with the object. "On" fills the blank correctly. Further, the second blank should refer to the location. Hence, "at" is the appropriate preposition. Lastly, "Receiving praise from" identifies the source of the recognition, i.e., her peers.
