To answer a question like this, you need to factor in many different ideas about what a shrew is, how beatrice is presented, and the context. It is important to mention both for and against points, even if it is to deny or criticize them. So, for this question, you could say that Shakespeare presents Beatrice as being a shrew through various examples, and show the effect this has on the other characters in the play, and also how this would affect the attitudes of the audience at the time - Shakespeare often included characters to make audiences wonder about their position in society or their attitude towards others, so this may be worth mentioning. To support this, you could bring in the idea that Beatrice was silenced at the end of the play (after her marriage she has no more lines), suggesting that such a character is dangerous to the order of society. It would also be acceptable to argue that Shakespeare doesn't present Beatrice as a shrew, or that this idea we get of her is as a mask to hide her true vulnerability. Here, you could again mention how this would impact the audience and other characters. To get as many marks as possible, it is important to argue both sides and not just describe them, showing your opinion on which is correct, and what Shakespeare's outcome was.
