The control group and the dependent variable are respectively; will be the 3 dishes placed on the road not under construction and the 3 dishes placed on the road construction site

<h3>What is a control Group?</h3>

A control group in an experiment is that which is made up of participants that do not receive the experimental treatment.

From the opening paragraph, it means when we are conducting an experiment, these people in the control group are randomly assigned to be in this group and as such they also closely resemble the participants or the individuals who receive the treatment.

In this question, the control group will be the 3 dishes placed on the road not under construction

The dependent variable is one that depends on other variables or constraints in an experiment. In this question the dependent variable will be the 3 dishes that were placed in the road under construction.

3. Did Truman's speech imply American military
weqwewe [10]

Answer:

That is right.

Explanation:

The Truman Doctrine comes from a speech delivered by president Harry Truman in Congress on March 12, 1947. The British government had announced that it would withdraw its economic assistance to the Greek and Turkish governments; Greece was battling a communist guerrilla.

Truman told congressmen that the USA would assume the responsibility of providing economic aid and military support to Greece. The Truman Doctrine says that the US will provide economic, military and diplomatic support to any nation under the threat of internal or outside forces (that meant communist insurgency or a direct Soviet threat in practice). In this way, he said goodbye to traditional isolationism and heralded a regular involvement in foreign affairs.
