1. The researchers had discovered several new types of materials.
- a. What is being done about inflation?
Explanation: The use of the past perfect tense ("had discovered") in sentence A1 indicates that the action of discovering new types of materials happened before the current moment. This corresponds to the question in sentence Ba asking about the current actions being taken to address inflation.

2. What department do you study at the University?
- c. How are these machines made?
Explanation: Sentence A2 uses the simple present tense ("do you study") to ask about the present situation of studying at a department in the university. This matches with the question in sentence Bc asking about the present process of manufacturing machines.

3. My office is being decorated at the moment.
- e. The plan was changed by the engineer.
Explanation: Both sentence A3 and sentence Be use the passive voice to describe an ongoing action. A3 mentions the ongoing action of decorating the office, and Be mentions the past action of the plan being changed by the engineer.

4. I have already written the programme.
- f. Einstein got his first job when he was 21.
Explanation: Sentence A4 uses the present perfect tense ("have already written") to indicate a completed action in the past with a present impact. This matches with the statement in sentence Bf about Einstein getting his first job at the specific age of 21.

5. They won't test this device.
