I think this is a high-quality question and the explanation isn't clear enough, please elaborate. Option C misses the use of "trigger" doesn't that change the intended meaning..

Based on induced stem cell techniques akin to those used for research purposes in mice to trigger regeneration of repaired cells, scientists are now well set to exploit stem cell theories into practical cures for a variety of dreaded ailments of man such as cancer, Parkinson’s disease, spinal cord injuries and multiple sclerosis.

A. Based on induced stem cell techniques akin to those used for research purposes in mice to trigger regeneration of repaired cells,
B. Based on induced stem cell techniques akin to those used for research purposes in mice so that the regeneration of repaired cells may be triggered,
C. Using induced stem cell techniques akin to those used for research purposes in mice to regenerate repaired cells,
D. Using induced stem cell techniques akin to those used for research purposes in mice, which triggers regeneration of repaired cells,
E. Using induced stem cell techniques akin to those used for research purposes in mice that trigger regeneration of repaired cells,


the quality of this sentence is above that of many other questions on this forum, the sources of which are unknown. I'll try to briefly explain why I chose C, and why I believe it is the right answer.

First of all, understand the meaning
the sentence starts with a long modifier, then after it comes the subject scientists. Well, scientists are not based on induced stem cell techniques. This is incorrect. Choice B has the same error.
Among C, D, and E:
D - relative pronoun which comes after mice. mice cannot trigger regeneration of repaired cells. it is rather stem cell techniques... that trigger the process..
E - demonstrative pronoun that is not correctly used here, and thus the same meaning error as in choice D can be inferred.
C is the best so far.

P.S. Why trigger is not actually need in C: "to regenerate" -> shows purpose. trigger I believe would have even been redundant here.

I think this is a high-quality question and I don't agree with the explanation. Triggering regeneration is not the same as regenerating. This idea can be shown through various scientific concepts, including RNA translation and neurotransmission.

I think this is a poor-quality question and I agree with explanation. The words used in the answers are not consistent. In the correct response C, the word "trigger" is not included, whereas it is in the other answers.

The correct answer should use trigger as the main verb. The response would be a variation on C, reading something like "Using induced stem cell techniques akin to those used for research purposes in mice to trigger regeneration of repaired cells," or "to trigger cell repair regeneration"

Although I chose the wrong answer, I agree with the solution. The reason why "trigger" can be omitted in this case is that the phrase - "induced stem cell techniques" is used. This makes the use of the word redundant.

Hi Brunel,

The answer choice E:
E. Using induced stem cell techniques akin to those used for research purposes in mice that trigger regeneration of repaired cells,

"that triggers" refers to research?

I do not agree with the above mentioned explanation.

They are using a technique that triggers cell regeneration.
Choice C changes the meaning of the original sentence, by implying the technique itself is regenerating the cells.
There is a difference between triggering an explosion and exploding - same here, there is a difference between triggering the regeneration and regenerating.

I think this the explanation isn't clear enough, please elaborate. Why is it that "Based on" is not a correct phrase to modify "scientists"? I was not able to choose between A and C.

I also think that "triggers" is essential in option C as the technique is triggering regeneration the cells are not being regenerated themself.

Why can contextually important word trigger be removed from the answer choice C
also I feel which and that used in option D and E are correct but D suffers from SVA issue while E doesn't so that's why I went with E

to trigger generation of repaired cells
to generate repaired cells both are same meaning 2nd one is distorting the meaning
