What are rhetorical questions?

A question that needs no answer.

Josh walks into the kitchen. He see's his sister standing at the fridge, eating from a container, with the name JOSH written in bold. She freezes. Josh asks, folding his arms, "What are you eating?"

In this, he (Josh) didn't need an answer, he can clearly see that she (his sister) was eating his food. It's more of a backhanded way to point something out and make the other person think.

A question asked which requires no given answer

A rhetorical question is when the person asking the question doesn't expect a direct answer but rather they are making a point. An example of a rhetorical question is if someone was running late the question would be "what time do you call this?" This question does not need an answer because they are just making a point that you have arrived at an unacceptable time and is expressing their annoyance.

The rhetorical question is a such kinda of question that isn't supposed to be answer at all

Rhetorical questions are questions where an answer is not expected, the question is being asked for effect or to make a certain point. For example, "What's not to like?" Is a rhetorical question as it is used to make a point, it's not meant to be answered.

A rhetorical question is a question to which the person asking the question does not expect a direct answer to that specific question. An example is “how could i be so stupid?” These questions are asked merely for effect , the answers to the questions are obvious or may immediately provided by the person asking the question.

A question asked for effect, to get the reader's attention that does not require an answer.

A rhetorical question is conducted in a manor that creates dramatic effect without out any real substance, rather than going straight to the point!

Rhetorical questions get your reader/audience thinking. They make you question what you really think about a subject and start sowing seeds of an alternative viewpoint. "How do you expect to achieve success if you don't work for it?" "What if we try a different approach?" Try using a rhetorical question in a title for an article to get your reader to question what they really think and begin to persuade them round to a different point of view from the get-go.

These are questions that do not require an answer or are used when the answer is already known and the speaker is trying to make a certain point

Questions that do not require an answer. 

Example: What sort of person am I? How I will I escape? Where am I? 

Makes the reader question themselves or the character's judgement.

A rhetorical question is a question that requires no answer. They are often used as a persuasive technique, for example in advertising campaigns and political speeches.

Questions that do not require an answer: i.e “Can you believe it?”

Rhetorical questions are questions which are not intended to be answered. They are often used for dramatic effect and not to gather information. The speaker or author may want to express an opinion on a topic, and this will be emphasised through the use of a rhetorical question.

For example, "What time do you call this?" is a rhetorical question. The speaker or author doesn't want to know what time it is, they are making a point that the person may have arrived late or at an unacceptable time.

A rhetorical question is one that does not require an answer. It's used to make a point, rather than to gain an answer.
