Please help me with the following:
A science class tested ways to clean water after an oil spill. Each group of students was given 100 mL of vegetable oil, 100 mL of engine oil, and 800 mL of water in a rectangular plastic container. Each container also held five floating wooden cubes (5 cubic centimeters each) representing animals in the water. Each group was tasked with removing as much oil as possible in a 20 minute period, leaving “clean water” in the container, using whatever tools they brought to class. The results of the “clean-up” are presented in the table below.
Group_Vegetable oil removed (mL)__Engine oil removed(mL)
__1____________10_______________________20
__2____________110______________________130
__3____________60_______________________40
__4____________80_______________________70
A. Group 1
B. Group 2
C. Group 3

The results of the experiment can be replicated by using any method of experimentation.
The results that support the claim are replicable by other scientists who follow the same procedures.
The claim is jointly issued from both a major university and an established government agency.
The claim is supported by at least ten scientists in addition to the original researcher
