Hmm good question. Well I would have to test it for where there are no living life. I would have to build another NASA in the County because there is plenty of room there. Mars is made out of Dusty Crust that is about 30 miles thick. And let's say that the desert's Dusty Crust is about 5 miles - 15 miles thick. That will give about the same amount of surface that mars has. So we would know what to build for a perfect lander to work on Mars. This isn't much but it is something.
I believe the answer is: Different scientists use different data for investigation.
I say that because different scientists have different equipment, ideas, and have different methods. I hope I was right and i hope it helped and i wasn't to late to answer this question.
In McMillen and Austin’s research (1971), participants who had lied were more likely to volunteer a large amount of time.
Explanation:
The research work conducted by Mcmillen and Austin in the year 1971, included college students as participants of the research. In this process they are asked to perform a small test of intelligence. One portion of them was asked to cheat and lie and the rest were left not to cheat.
After finishing the test, the participants were asked to help the administrator to conduct the next round of test for other slot of participants. It was seen that the students who did not lie or cheat, helped them in their work for about 2 minutes. But students, who did lie, stayed and helped for 53 minutes.
