Answer:
A. The connotation of the word careless suggests that Marta doesn't pay attention to her things.
Explanation:
Careless, as used in the passage, shows that she was not being careful with her glasses thus she ended up breaking them. Since the passage said that she usually broke them within a week, we can infer she isn't careful with any pair of her designer glasses she has bought. Therefore, it cannot be B because she does NOT really care about her things, and C is off-topic because it never says that she prefers designer sunglasses, only that that is what she always bought.
D. to establish a uniformity of presentation that enhances communication
Here is the answer the guy answer is absolutely despicable
1. Sometimes it is more difficult to concentrate if you use active listening skills because you have to simultaneously understand what you are being told and reassure the speakers that you understand them by using verbal affirmations like for example "Sure", "I understand", "I see", etc. So, for me it sometimes caused me trouble trying to use active listening skills like nodding, establishing eye contact or paraphrasing what the speakers said in order to show them that I was involved.
2. Some of my friends and family responded differently to my active listening and seemed to be more excited about what they were talking about because I seemed to be really interested in what they had to say.
3. I also felt a little bit differently because active listening is more demanding than passive listening and it required greater effort from my part.
That's is why god gave us two ears and one mouth.
