Answer:
OA. I got an e-mail telling me I can find my soulmate on the Internet.
Step-by-step explanation:
The first answer makes complete grammatical sense. There is nothing wrong with it.
The second answer, however, does not make sense. The first sentence of the second answer makes sense: "I got an email telling me I can find my soulmate." But, the second sentence doesn't make sense: "On the internet." This is called a dangling modifier. It is describing or giving more detail about something, without having the actual thing. What is on the internet? The sentence does not work on its own, which is why the first answer, with both sentences combined, is correct.
