Answer: Experimenter bias.
Explanation: Experimenter bias is the condition which describes a person as a part of experiment who is influencing the outcome of the experiment so that the desired or preferred results can be obtained.Experimenter bias is also known as research biasing.
The example mentioned in the question where Brian is conducting the study with sharing his views with the participants that he expects girls should perform better than boys in the experiment is example of experimenter bias.
The actual experiment should have been conducted without any thought sharing or acknowledgement which would have produced unbiased outcomes.But according to Brain's study, the expectations are conveyed ,therefore it will influence the result of the experiment as it becomes biased.

Explanation:
The first human spaceflight named Vostok 1 was launched on April 12, 1961. This spaceflight took along with it Yuri Gagarin, a Cosmonaut who came from the Soviet Union. Thus this scientist was the first to ever travel to space and enter into orbit.
The formal end of the space shuttle program was marked in August 31, 2011. The last shuttle, STS-135 that was flown by Atlantis was retired on July 2011. So the time duration between the first human spaceflight and the end of the space shuttle program spanned some 50 years.
