If there was a natural disaster and the people that were in this disaster were supposed to be there. there were 3 people in the back of the cabin, two were in the front of the cabin. the cabin was on a mountain and there was snow all around the cabin. the windows had been busted and the interior of the cabin was burnt with wires hanging. no foot prints were outside the cabin and no vehicles had been on the mountain for years. what type of disaster happened?

Researchers conducted an experiment to identify the effects of three different hand sanitizers on the growth of bacteria. the researchers grew one type of bacteria in twenty-four identical covered petri dishes. then, they opened eighteen petri dishes and applied the three hand sanitizers to six petri dishes each. they left the remaining six petri dishes closed as a control group. when the researchers measured the growth of bacteria two days later, the six dishes that had no hand sanitizer showed the least amount of bacterial growth. the researchers concluded that not using any hand sanitizer would lead to the least bacterial growth. which statement best explains why the researchers’ conclusion was not justified? the experiment tested too many variables. the control group was not treated the same as the experimental group. the sample size of twenty-four petri dishes is not large enough. the single type of bacteria is not adequate to make any conclusions.
