Three main factors came together to cause Hurricane Sandy:
1. A huge storm with winds gusting up to 90 mph (145 kph) was set to make landfall somewhere on the East Coast that Monday night.
2. But a storm like Sandy would normally be losing steam by now as it moved into colder, less energetic waters. In this case, however, a trough of low pressure dipping down from the Arctic was feeding the hurricane, actually strengthening its intensity as it moves northward. (Higher tides because of a full moon may also increase flooding from the storm.)
3. The third weather factor feeding Sandy, a high-pressure system, was pushing the hurricane onshore.
There is some debate about whether climate change had anything to do with Hurricane Sandy and those like it that have behaved unusually but the research is inconclusive.
Hope this helps.

The Saudi Arabia politics are take place in the context of a totalitarian absolute monarchy with some Islamic (Wahhabi Islam) lines, and the King is both the Saudi Arabia's head of state and absolute monarch (i.e. he is the head of government). The King also serves as the head of the Saudi royal family, the House of Saud, which is also why the country bears the name that it has.
<span>Both radar and sonar locate objects from the echo of a signal that is bounced off the object. Radar uses radio waves, which are a type of electromagnetic energy. Sonar uses the echo principle by sending out sound waves underwater or through the human body to locate objects. Sound waves are a type of acoustic energy. Because of the different type of energy used in radar and sonar, each has its own applications.</span>
I would say D.
because you can’t count on foraging to feed 100 people, whereas agricultural growing of food is more effective when you have more people. you can plant 100 seeds, but you can’t guarantee to find 100 berries while foraging. hope this helps!
