Answer:
Passive voice
Explanation:
Whereas the active voice has a subject that performs an action on a verb, the passive voice contains a subject that is acted upon by a verb. The example above was written in the passive voice. "The pirate" is the subject in this sentence. It was acted upon by the verb "hoisted". An active form of this sentence will be, "The pirate hoisted the sails".
A past participle, a preposition, and a conjugated form of the verb, "to be", are coined to form the passive voice. The past tense of the verb, "to be" which is "were" was coined to the past participle, hoisted. The preposition, "by" also helped in completing the meaning of the sentence.
There are several different reasons depending on the perspective you look at it.
If you're looking at it from the government perspective, then this was due to the fact that they wanted to get rid of the tradition and have a complete take over of the culture by getting rid of it.
Other explanations are that they wanted to switch an alphabet or genuinely wanted to simplify the actual characters.
Hope this helps!
