Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes drawing a conclusion. hint: to draw a conclusion, you decide if the data support or refute the hypothesis. using a wrench to remove a bolt from a tire abby watched her sister change a tire. one bolt seemed stuck, so she took a hollow pipe and put it over the wrenchs handle to make it longer. abby wondered why this helped her sister remove the bolts. she predicted that the longer handle allows a person to use less force to turn the wrench. to test her idea, abby and her sister drilled nine small bolts into a wooden board. abby then attached a spring scale to a normal wrench. as she pulled the spring scale at a right angle to turn the wrench, she measured the force it took to remove a bolt. she repeated this with two more bolts and averaged the three measurements. then she put a short pipe over the handle and removed the next three bolts. finally, she put a long pipe over the handle and repeated the procedure. when she compared the three averages, she found that the longest handle took the least force to remove the bolts, while the unmodified wrench took the most. abby concluded that the longer a wrenchs handle is, the less force it takes to turn it.

Explanation:

The key - part for drawing a conclusion is where Abby decides if her data supports her hypothesis. She compared the forces for different handle lengths and determined a relationship. The sentence "When she compared the three averages, she found that the longest handle took the least force to remove the bolts, while the unmodified wrench took the most. Abby concluded that the longer a wrench's handle is, the less force it takes to turn it." shows her drawing a conclusion based on the data from her experiment.

Answer:

When she compared the three averages, she found that the longest handle took the least force to remove the bolts, while the unmodified wrench took the most. Abby concluded that the longer a wrench's handle is, the less force it takes to turn it.
