Answer:
The sentence which contains a fallacy is:
B. Unless everyone in the U.S. including our grandparents can successfully use social media, we will be left behind.
Explanation:
A fallacy takes place when our logic is flawed, which undermines the strength of our argument. We have an example of a fallacy in letter B. Let's analyze why.
According to sentence B, we only have two options:
1. Have everyone successfully use social media;
2. Be left behind.
The writer of the sentence makes it seem that these are the only two ways to go. We either do A, or we'll get B. However, that is not true. There are several other ways to go. Even if our parents do not learn to successfully access social media, we can still stay ahead. Therefore, we can safely say that letter B has a fallacy.
I personally would choose D, because if you chart it out, you could weigh both sides and see things clearly.
The transition word which is not correctly used in the passage is moreover.
As you can see in this sentence (<span>Moreover the invention of television and digital media, such as the Internet, most ads appeared in newspapers, magazines, and the radio.), something is wrong - the sentence doesn't sound natural or grammatical. This is why that word is the one which is used incorrectly, whereas the other sentences are good.</span>
