II. Open the brackets and choose the correct form of the verb:
1. We analyzed the data obtained after we (finished, had finished) our experiments.
2. We (discuss, will discuss) all the problems tomorrow.
3. If these two types of devices (were mixed, will be mixed) a compact and power-efficient product might be created.
4. Amplitude statistical characteristics (have discuss,
have been discuss) already when considering measurement errors.
5. The exact operation of some devices (cannot rely on, cannot be relied on) due to their being slightly influenced by the changes in temperature.
6. If the circuit (possesses, will possess) no resistance, the back e.m.f. will be constant in magnitude.
7. The semiconductor specialists proved that this vertical structure (allows allowed) the base to be doped with germanium to get the highest speeds.
8. By adding a heavily doped region below the collector contact the scientists believed that they (will achieve, would achieve, achieve) a low collector resistance.
9. The students (did, were doing) the laboratory works from 10 o’clock till 12.
