The given scenario is an example of a selection-history effect.

Option D

<h3><u>Explanation:</u></h3>

In group-based research, selection-history effect assesses the behaviour displayed by the test subjects before and after the test. Since it is a history threat or effect, it means the outcomes of the results will be affected by the individual’s past experiences.

The individuals in the research have different pasts, and while the control group may have performed worse, it shows that there are other factors influencing motor control. It may be a bad experience with bad driving at a younger age, or some have a phobia to driving.

State two main arguments that Mr. Wong makes as to why the Chinese Exclusion Act should not be passed.
valentina_108 [34]

Based on a historical perspective the two main arguments that Mr. Wong makes as to why the Chinese Exclusion Act should not be passed include the belief that America is <u>the only place where every class and race of human being can live and thrives.</u>

<h3>Who is Wong Chin Foo?</h3>

Wong Chin Foo was a famous Chinese American who was known for his activism roles and journalism lecturing activities.

For the major part of his stay in the United States, he fought for the liberation of the Chinese people living in the United States of America.

In his bid to ensure that the Chinese Exclusion Act did not pass, Wong Chin Foo gave two major arguments to the people in positions of decision.

These two main arguments are:

  • The United States is the only place every class and race of human beings can live and thrives with peace and joy.

  • Also, he argued that American people generally do not wish to create a caste system where many men cringe and crawl before few others.

Hence, in this case, it is concluded that Mr. Wong Chin Foo argued consistently to ensure the Chinese Exclusion Act should not be passed.
