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.
(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
(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
[spoiler]Can someone please explain how and at a lower cost in D makes sense after a comma.. I thinkd it cant act alone and hence cannot be right answer.. I understand the other sentences have comparison issues but isn't this a wrong usage of and??? [/spoiler]
