1. including treating cancer.......
2. including treating cancer, relieving arthiritis, and dulling pain.
3. including the treatment of cancer, relieving arthiritis, and dulling pain.
4. which includes treating cancer, relieving arthiritis, and it is able to dull pain.
5. which includes treating cancer relieving arthiritis, and dulling pain..
I got this one from Kaplan and it is a simple parallel consturction question, so I am going to spare u the trouble of solving it. 2 and 5 both solve the parallel consturction error and because 5 uses "which includes" which is singluar and doesnt go with the plural "roles", the answer is 2.
Now my question is this.. Suppose 5 was rephrased as
5. which include treating cancer, relieving arthiritis, and dulling pain.
what would the correct answer be?????
