Thanks to modern technologies, like the Internet, the customer reviews have gained a lot of importance for companies and they aim to receive good feedback from them. For example, when you are going to buy something on Amazon, would you buy a 1-star item or a 5-star one? Some companies have even hired people to write good reviews for their products online. So, instant communication and sales for customers is one of the most important factors when rating a product or a company because it shows: (1) Businesses can be available for customers 24 hours a day.  (2) Customers can purchase goods and services online.  and (3) Customers can give feedback to producers instantly

Answer:
I think the central idea of the passage is that the family Otzi's father is common in Europe.
Explanation:
My justification for my answer is that his DNA kind of matched the one of the people living in the Neolithic Age. This shows that maybe he was a descendant of those people.
I think the first answer is wrong because people of the Neolithic Age were from the past and I don't think DNA existed by then.
And the think the second is wrong because his mother's family was just rare it wasn't complex.
Finally the last is wrong because the DNA wasn't so hard to test it was also easy to compare it because there were other samples to be compared with.
That leaves us with the last answer as correct.

Answer:
Only 1) is true because selective reporting data is not considered to be UNETHICAL in research behavior BUT non-existent data is UNETHICAL.
Explanation:
Selective reporting of data is a process where by results are reported based on selections made from the study. It involves tweaking hypothesis made from the study.
Non- existent data is where results that are not from the original study are added to the result.
 
        
             
        
        
        
The economic term is the opportunity cost.
The concept of opportunity cost is a relatively inexpensive and relative measure that involves people's preferences, so it varies from person to person. It is a question of comparing what is left over when making a decision.
In Katie's case, the opportunity cost of the money she saves to buy a car is what she fails to do with that money. For example, she stops investing in stocks, fails to make a trip, etc.
All decisions involve an opportunity cost. Taking another example, the opportunity cost of studying for the test at the end of the week is measured by the loss of leisure you would have. However, the decision to study for the test is chosen because it is more valuable.
