Question 29: Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions: Up the World War II almost all important research in physics had made in universities, with only university funds for support.

=> It was not until World War II that most of the important research in physics was conducted

university, supported only by school funds. Answer C is structurally incorrect:

Do/ conduct/ undertake research: conduct, do research.

Ex: I’m still doing research for my thesis.

Next is the verb that needs to be conjugated in the passive form because the research must “be” done, do. Therefore, the answer should be changed to: been done/ practiced/ committed.
