(A) The recent discovery of a red oak tree sap that is anticipated to advance experimentation with natural substances in order to create cancer medicines will be able to provide chemists with a more potent mixture to work from than other trees and at a lower cost ........ This comparison is clumsy because this option attempt to compare the red oak tree with other tree under tow factors....

(B) The recent discovery of a red oak tree sap is anticipated to advance experimentation with natural substances in order to create cancer medicines and will be able to provide chemists with a more potent mixture to work from at a lower cost than the sap extracted from other trees

(C) The recent discovery of a red oak tree sap, which is anticipated to advance experimentation with natural substances in order to create cancer medicines, will be able to provide chemists with a more potent mixture to work from at a lower cost than other trees

(D) A recently discovered red oak tree sap, which is anticipated to advance experimentation with natural substances in order to create cancer medicines, will be able to provide chemists with a more potent mixture to work from than the sap extracted from other trees can, and at a lower cost

(E) A recently discovered red oak tree sap, which is anticipated to advance experimentation with natural substances in order to create cancer medicines, will be able to provide a more potent mixture to work from than other trees and to decrease the cost ..... This correctly use parallelism ... will be able to X and to Y .... and concise comparison ...

I will go with E

D

Comparison MUST be logical and parallel.

See the options A, B, and C in which "Discovery has been compared with trees and/or sap". A< B, and C are out.

In SAP has been compared with TREES.

------oak tree sap................than other trees..

Answer is thus [spoiler]D.[/spoiler]
