Cite Multiple Pieces of Textual Evidence Practice Test
•10 QuestionsRead the passage, then answer the question.
In science class, Ms. Ibarra asked students to test which paper towel brand absorbed the most water. Each group received the same tools: a measuring cup, a tray, and three paper towel squares cut to the same size. The directions said to pour exactly 50 milliliters of water onto each square and to record how much water dripped into the tray after 30 seconds. Ms. Ibarra reminded everyone that “a fair test changes only one thing.”
During the lab, one group quietly swapped in a thicker square from home because they thought it would “make the results clearer.” Another group squeezed the towel after 30 seconds to “see what was really inside,” even though the directions said not to touch it. When the class compared data, the numbers were all over the place. Ms. Ibarra did not accuse anyone, but she asked the class why their results did not match. She pointed to the directions again and said, “If we want conclusions we can trust, we have to trust the process.” She then offered a redo lab, but only if groups wrote a short plan explaining how they would control variables.
Question: Which choice cites multiple pieces of textual evidence that best support the claim that uncontrolled variables caused the inconsistent results?
