We are going to use the ideal gas law. First, convert 475 kPa to Pa because the ideal gas law uses SI units. This will be 475,000 Pa.
Rearranging the ideal gas law, we get P1V1/T1 = P2V2/T2. Now plug everything in and solve for P2: (475,000)(4)/(290) = (P2)(6.5)/(277)
Answer should be positive 1 2/3

The correct answer to this open question is the following.
If what you are asking is to write the first lines of a traditional fairytale, but changing that traditional approach to something different, innovative, or funny, then we can help you with the following.

Somebody says this happened in the Middle Ages, but who cares. Not me. The thing is that there are a couple of morals in this story that could make you think about your role in life.
This is a story about character and determination. No beautiful towns, no bords, farm animals in a cozy village next to a beautiful river on a shinny hill. No handsome prince, no attractive princess. Just crude and raw day-to-day issues of life that would make you think how fortunate you are to live in different times...
