Answer:
B, they need as much as they can get.
One foot is equal to 12 inches, so 12 times 12 will give you the number of inches in 12 feet.
12 x 12 = 144
If there are 12 inches in a whole foot, then there are half that many in a half foot, so there are 6 inches in a half foot. Now you have to had 144 inches to 6 inches.
144 + 6 = 150
There are 150 inches in 12 1/2 feet.
Hope this helps!

Memphis and Thebes. Both was main cities and both located on the Nile River.
Also, I don't know why, but it also says Cairo and Alexandria were both on the Nile River. I believe these two would be correct.
In the absence of an atmosphere, Earth’s surface temperature would be about –18°C, or 0°F, which is way too cold for life. Greenhouse gases have just the right molecular structure to absorb infrared radiation that the Earth emits. It re-emits most of that infrared energy in all directions, warming the atmosphere to its comfortable average temperature of 15°C (60°F). So the greenhouse effect is a good thing.
