When you are not sure of a person's gender, then the most appropriate pronoun to be used is 'they/them'. Although 'they/them' is generally used as a plural pronoun, in case of gender ambiguity, 'they/them' is widely accepted, and can be considered gramaatically correct. 

Some of the gender neutral pronouns include the following:

• It
• They
• Them
• Ze/zir
• Xe/xem

Using Pronouns in correct manner has the following benefits:

• Avoids repetition: Using pronouns appropriately can avoid repeating the nouns.
• Improves flow of sentence: Using pronouns help maintain the flow of the sentence and improves clarity.
• Supports sentence structure: Pronouns play important role in subject-verb agreement and sentence construction.

Pronouns are generally used after the first sentence, or after the first instance of Noun. Once the Noun is stated or the subject is introduced, Pronouns can be used as a substitute of the Noun. For example, Riya studies in Class 6. Her favourite subject is History. Here, the Pronoun 'Her' is used in the second sentence as a substitute to the Proper Noun, which is Riya.

Pronouns belong to the Parts of Speech section of English Grammar. Pronoun is one of the eight traditional types of Parts of Speech. The other seven types pf Parts of Speech include Noun, Verb, Adjective, Adverb, Preposition, Conjuntion and Interjection. 

Passive voice is a type of sentence in which the subject receives the action instead of becoming the doer. Here, the focus will be on the object, and there will be a little focus on the subject or doer. I.e. A mango was eaten by Ram. In this sentence, the emphasis is on Mango instead of Ram. 

Active voice is a structure of a sentence where the doer is the subject that performs the action expressed by the verb. Here, the emphasis will be on the doer, making the sentence clear and direct.

For example, Siya was riding a bicycle. Here the emphasis is on Siya instead of on the bicycle.

The passive voice writing style is suitable for formal writing, scientific reports or any such situation where the subject is less important than the object, like the experiment was conducted. It highlights the action or result. In such style of writing object is doer instead of subject.
