Hello there. today I am going to be telling on why you should buy and apple watch. There are many great reasons to buy one. A few of those reasons would be that you can send and receive calls from it and not even have to use your phone. Another reason would be that it has a health monitor so you would know how much you need to work out in a day. These are some reasons why you should buy an apple watch.
I hope this will be a good enough answer for you :)

B. The sentence that has an error in usage is the following one: Sometimes being a man simply means helping others bare their difficult burdens. The word "bare" in this sentence should be the word "bear" which means "to help endure or carry."
