A nuclear test explosion was detonated recently in the Pacific Ocean, creating a substantial blast with a yield of 7.3 kilotons, or magnitude 5.1 on the Richter scale if it had been measured as an earthquake.

A. A nuclear test explosion was detonated recently in the Pacific Ocean, creating a substantial blast with a yield of 7.3 kilotons, or magnitude 5.1 on the Richter scale if it had been measured as an earthquake

B. A nuclear test explosion detonated recently in the Pacific Ocean created a substantial blast with a yield of 7.3 kilotons, or magnitude 5.1 on the Richter scale as an earthquake

C. When a nuclear test explosion was detonated recently in the Pacific Ocean, it created a substantial blast with a yield of 7.3 kilotons; qualifying it to be magnitude 5.1 on the Richter scale if an earthquake

D. A nuclear test explosion detonated recently in the Pacific Ocean created a substantial blast with a yield of 7.3 kilotons; an earthquake with that force would measure as magnitude 5.1 on the Richter scale

E. When a nuclear test explosion was detonated recently in the Pacific Ocean, its substantial blast, which would be deemed magnitude 5.1 on the Richter scale for an earthquake, yielded 7.3 kilotons

Dear sillyboy,

I'm happy to respond. :-)

I don't think this is a high quality question.

A. A nuclear test explosion was detonated recently in the Pacific Ocean, creating a substantial blast with a yield of 7.3 kilotons, or magnitude 5.1 on the Richter scale if it had been measured as an earthquake
This is fine. The explosion yield is in parallel to the Richter magnitude---two different ways to measure powerful things. Presumably this is perfectly correct parallelism---if it's not, we would need advanced scientific knowledge to determine that.

B. A nuclear test explosion detonated recently in the Pacific Ocean created a substantial blast with a yield of 7.3 kilotons, or magnitude 5.1 on the Richter scale as an earthquake
I think this version would be clearer if the participial phrase "detonated recently in the Pacific Ocean" were set off in commas. Again, it is not obvious that this is wrong---we would need specialist knowledge to determine that.

C. When a nuclear test explosion was detonated recently in the Pacific Ocean, it created a substantial blast with a yield of 7.3 kilotons; qualifying it to be magnitude 5.1 on the Richter scale if an earthquake
This one, admittedly, is a little awkward. We can reject this.

D. A nuclear test explosion detonated recently in the Pacific Ocean created a substantial blast with a yield of 7.3 kilotons; an earthquake with that force would measure as magnitude 5.1 on the Richter scale
Again, I would like to see the participial phrase set off in commas, but other than that, this is fine.

E. When a nuclear test explosion was detonated recently in the Pacific Ocean, its substantial blast, which would be deemed magnitude 5.1 on the Richter scale for an earthquake, yielded 7.3 kilotons
An unorthodox word order, and a little indirect. We can reject this.

I think the question writer was making many assumptions about what the general reader would know about the subject matter here. In this way, this is not a very GMAT-like question.

Let me know if anyone has any questions about what I've said.

Mike :-)
