Answer:
The answer is C.
Explanation:
In experimental research, the independent variable is unchanging and may or may not have an effect on the dependent variable (in this case, the test scores). For this reason, idependent variables are also called explanatory variables.
An easy way to remember the difference is that <u>independent variables change the outcome of dependent variables. </u>

The Phoenicians were the greatest traders in the ancient world for the period between 1000 B.C.E. and 600 B.C.E. These were highly skilled shipbuilders and sailors built strong and fast sailing vessels to carry their goods. They learned how to navigate and how to use the North Star to sail at night. It is possible that they even sailed as far as Britain and around the southern tip of Africa.
To fight off pirates who often harassed trading ships, the Phoenicians designed special warships to accompany their trading fleets. Oarsmen would propel a sharp ramming device at the front of the boat into an enemy's vessel, putting a hole into it that would cause it to sink.
To expand in trading, the Phoenicians also built outposts that later became great cities in their own right. The most famous of these outposts was Carthage (located in modern-day Tunisia). Carthage eventually became wealthy and powerful enough to challenge the Roman Republic.
Phoenician merchants acted as middlemen for their neighbors. They transported linen and papyrus from Egypt, copper from Cyprus, embroidered cloth from Mesopotamia, spices from Arabia, and ivory, gold, and slaves from Africa to destinations throughout the Mediterranean.
