Final answer:
The two examples of a request are invitations for specific actions: participating in a recycling workshop and assisting with profiling age groups. The others are offers or comments.
Step-by-step explanation:
The two persuasive messages that are examples of a request are:
- Please take part in the recycling workshop at your company this weekend.
- We need your assistance in profiling the age groups in the district.
These messages are requests because they both ask the recipient to engage in a specific action: attending a workshop and assisting with profiling duties, respectively. The other messages either offer information or express a reaction to something that has occurred, such as giving a discount or commenting on a surprise regarding billing, rather than asking for a specific action to be taken by the recipient.
