Put the following surfaces in descending order from those surfaces that have the highest albedo to those surfaces that have the lowest. I. clouds II. ice sheets III. forest IV. asphalt pavement a. IV-III-II-I b. III-I-IV-II c. II-IV-I-III d. II-I-IV-III

d. II-I-IV-III

Explanation:

The albedo of the ice sheets s the highest and that of the forest is the least or the lowest.  The forest covers about the 12% of the landscape and the 29 of the surface area of the planet thus have an albedo of 0.017. While that of the asphalt payment is the 0.18 to 0.35.

This is all you, but i can give you some topics that you could try. if it rained when you want to do something outdoors, it 'limits' that human activity. maybe you want to do an experiment that goes throughout the whole year and you have to have above freezing the entire year. this 'limits' your activity. i thought of those just off of the top of my head. something that gets to me that might be getting to you is you are thinking too hard about what to do. think simply, and if it is too simple, then bump it up just a little bit.
