Continuing on from the previous question, since you're writing a solicited proposal that goes to Thingamajigs Inc., why should you include a brief description of the problem facing Thingamajigs Inc. and a short explanation of why it needs to be solved?

Question $5$ options:

a$)$

Trick question! You actually should write a lengthy description of the problem and an detailed explanation of why it needs to be solved.

b$)$

You need to demonstrate that Widgetmaster Corp. is the best choice because your company understands both the problem and the reason why it needs to be solved.

c$)$

The RFP$\text{'}$s author has probably forgotten about the problem and why it needs to be solved. You need to remind her$/$him$.$

d$)$

Trick question! You actually should omit both.

The reader at Thingamajigs Inc. already knows all about the problem and why it needs to be solved, and s$/$he doesn't need any reminders.
