d:that the investigated changes in working conditions effects on workers' performance.
e:to investigate what the effects changes in working conditions would have on workers' performance
The context is to investigate the effects of X (changes brought to working conditions) on Y (worker's performance). (i couldn't put this in much simpler way :()

If you get that right there is no better option than B expressing clearly.

A - as to their effects is wrong
C - effects workers' performance are that changes in working conditions - too wordy and not clear
D - investigated changes in working conditions effects on workers' performance. - this changes the intended meaning, moreover its not clear.
E - to investigate what the effects changes - wrong. Word placement what effects the changes is the right one

IMO B - More concise & clear in meaning.

Expected to do two things - to increase ... and then to stabilize - C D E are out.
A - which seems to refer to day - not clear - wrong

IMO B.

Question 1 imo B

In the mid-1920's the Hawthrone Works of the western electric company was the scene of an intensive series of experiments - in this sentence we already know what was going on at Hawthrone Works hence we do not need "that" as the following information is non-essential. therefore, A and D are out

C doesn't even make proper sense
E same as C


question 2

imo B

The yield of natural gas from Norway's troll gas feeld is expected to increase annually until thear 2005 and then to stabilize at six billion cubic feet a day, which will allow such an extraction at least for 502years' production.

red marks parallelism

C,D and E out

between A and B - B (concise + in A ,which modifies day which is irrelevant)
