Ken wants to add the following sentence to the third paragraph (sentences 8-13). "Although this 360-degree view allows people to watch the fish from practically anywhere inside their watery habitat, visitors can catch a glimpse of much more than fins, gills, and tails."

Where is the best place to insert this sentence?

F. After sentence 10

G. After sentence 11

H. After sentence 12

J. After sentence 13​

F. After sentence 10

Explanation:

To begin with, this is paragraph 3:

"(8) The AquaDom has some other features like a two-floor elevator that is  transparent. (9) It allows visitors to ride up the length of the tank to gaze at the fish  from every possible level. (10) Though one might guess that the elevator rides along  the outside of the tank, it is actually situated in the tank’s center, the clear walls  giving riders a truly up-close-and-personal experience with the aquatic residents.   (11) The elevator lets visitors observe the dedicated tank divers hard at work.  (12) This includes watching the divers feed the inhabitants and clean the massive  tank. (13) Getting an inside look at people performing this unique job is as  interesting as watching the swarms of fish."

Now, if we add the sentence Ken wants to add to the third paragraph, he should rewrite it like this:

"(8) The AquaDom has some other features like a two-floor elevator that is  transparent. (9) It allows visitors to ride up the length of the tank to gaze at the fish  from every possible level. (10) Though one might guess that the elevator rides along  the outside of the tank, it is actually situated in the tank’s center, the clear walls  giving riders a truly up-close-and-personal experience with the aquatic residents. (F) Although this 360-degree view allows people to watch the fish from practically anywhere inside their watery habitat, visitors can catch a glimpse of much more than fins, gills, and tails. (11) The elevator lets visitors observe the dedicated tank divers hard at work.  (12) This includes watching the divers feed the inhabitants and clean the massive  tank. (13) Getting an inside look at people performing this unique job is as  interesting as watching the swarms of fish."

See how it makes a lot more sense? Therefore, your answer is F.
