Answers: (please read the descriptions)

An email giving details of five broken  vases received from a seller:

Claim - part of me wants to say that this is a request, but nothing in the sentence says that the customer wanted to be refunded or receive a new product. With this knowledge, this is most likely a claim since the customer is making a claim about the product received. However, I could be incorrect.

A letter outlining an idea to increase  a company's sales by 10 percent:

Proposal - This is an idea, not a plan in effect. Therefore, it is a proposal.

A letter complaining about the  service at a dry cleaner:

Claim - Once again, I want to say that this is a request, but nothing in the sentence says that the customer is requesting a refund for the service, so I am going to say that this is a claim since the customer is making a claim about their service. Once again, I could be incorrect.

An email asking employees to  attend a charity event:

Request
