Answer: order of test items
Explanation: An independent variable is a variable that is specifically manipulated by a researcher to investigate whether it consequently brings about change in another variable. The other variable, which is measured and predicted to be dependent upon the independent variable, is known as the dependent variable.
In the experiment above, the independent variable is the order or arrangement of the test items. The instructor gave two sets of order to two groups of students to study effect of the order on test scores. The effect on the test scores may be dependent on the order the tests were arranged.

<u>Answer:</u>
Telemarketers know that anyone who agrees to listen to a pitch is more likely to buy the product, thanks to the foot-in-the-door phenomenon.
<u>Explanation:</u>
- 'Foot-in-the-door phenomenon' is the phenomenon of persuading someone to agree upon a big request after them 'agreeing to a small request'.
- This phenomenon is based on a principle that when a person agrees upon a small request, there is development of bond between the requester and request.
- This development of bond will help the requester to make request agree upon his request.
- In the above case, if a person agrees to listen to the polite pitches of telemarketers, there is agreement on small request and the probability to buy a product will increase because there is development of bond between them.
