Describe your problem better, what do you want answered?…. The question in the pic seems of personal opinion.
This is what the passive version of this sentence would look like:
The statue of David was sculpted by the famous artist and sculptor Michelangelo in Italy in the early 1500s.
In English, usually the word that is placed in the beginning of a sentence is the most prominent one, and the most important one as well. It is where the emphasis of the sentence is. Having this in mind, the best reason for the writer to revise this sentence to be in the passive voice is to emphasize <u>the statue.</u>
Cain was always overshadowed by Able and that upset him so he decided to get rid of them so he's no longer overshadowed
“Or” is a coordinating conjunction: it is included in the saying FANBOYS. If you haven’t heard of this, I can explain another way. A coordination conjunction connects words and phrases that are independent or of equal rank. So, the word “or” represents another option.
Hope this helps! :)
