Question

you read more closely the following sentence from the article: \9. in a true emergency, massive cell phone usage can overload phone systems, crippling critical official and emergency communication.\ how do you think the word crippling affects the meaning of this sentence?
○ it reinforces the point that cell phones have zero negative aspects.
○ it emphasizes how disastrous an emergency situation can become if cell phone systems cant be used.
○ it introduces the concept that many people call emergency numbers erroneously.
○ it proposes an idea to local law enforcement to remedy the issue of faulty phone systems.

Explanation:

1. Analyze Option 1: The sentence talks about a negative impact (overload, crippling communication) of cell phone usage in emergencies, so "zero negative aspects" is wrong.
2. Analyze Option 2: "Crippling" means severely damaging or disabling. In an emergency, if communication systems are crippled (due to overload from massive cell phone use), it makes the situation more disastrous as critical communication fails. This matches the meaning of "crippling" here.
3. Analyze Option 3: The sentence is about system overload from usage, not about erroneous emergency calls. So this option is irrelevant.
4. Analyze Option 4: The sentence is describing a problem, not proposing a solution to law enforcement. So this option is incorrect.

Answer:

B. It emphasizes how disastrous an emergency situation can become if cell phone systems can't be used.
