Answer:The technique use in this study is referred to as a double blind

Explanation:

A double blind study is the one that both participants and experimenters or researchers are not made aware who is given a certain treatment.

In double blind researchers will not know if what they are receiving is part of the test itself as they interact with participants or they are receiving a placebo.

This process is useful to eliminate and avoid bias results.

For example, in the above text the effect of caffein on attention is being tested so the researchers will not know whether the drink given to them is actual for the test or just the placebo , they don't know who is in control of the experiment.

ValentinkaMS [17]

Answer:

A second interpretation from the 2005 CAT scan suggested that Tutankhamen’s broken leg occurred during:

Carter’s recovery of the body.

Explanation:

It was English Egyptologist Howard Carter, along with his team, who on October 28, 1925 excavated the mummy of King Tutankhamen. There have been several theories concerning the injuries found and the possible cause of Tutankhamen's death. For instance, his leg injury was believed to have occurred during a chariot race.<u> However, a second interpretation from a CAT scan performed on the mummy in 2005 claims the leg was likely to have been broken when Carter was excavating the body. Still, different researchers defend different theories. Nevertheless, the belief that Tutankhamen died violently has been almost completely refuted.</u>
