(A) that offer substantially higher pay, but requiring long hours, physically taxing labor, or relocation to remote, sparsely populated areas, or less physically intense though lower-paying jobs
(B) that offer substantially higher pay, but that require long hours, physically taxing labor, relocation to remote or sparsely populated areas, or less physically intense and lower-paying jobs
(C) offering pay that is substantially higher, but that requires long hours, physically taxing labor, or relocating to remote, sparsely populated areas, or lower-paying jobs that are less physically intense
(D) that pay substantially higher but requiring long hours, physically taxing labor, relocating to remote or sparsely populated areas, and lower-paying jobs that are less physically intense
(E) offering substantially higher pay, but requiring long hours, physically taxing labor, or relocation to remote, sparsely populated areas, and less physically intense, but lower-paying jobs
Why say jobs that offer ? would be much more concise to say "jobs offering" and GMAT like concision. ABD out
Then it's between C and E, the problem with C is "that requires" seems to refers back to pay, but it is none sense.
E is perfectly clear as it dont has this problem that C has, plus it is the only option left so ^^
