dv_dheeraj Posted September 8, 2008 Share Posted September 8, 2008 I will go with D Again we a being tested for summative modifiers it is the practice of working overtime and not the overtime itself which is causing errors in judgement. Rules out ABC. of D and E i choose D because E has a redundancy can potentially. Potential should be enough. Quote Link to comment Share on other sites More sharing options...

dv_dheeraj Posted September 8, 2008 Share Posted September 8, 2008 OA is E ! can anybody explain why C is incorrect? I think this is an often debated q whose OA varies from D to E but one guru has endorsed D:) http://www.www.urch.com/forums/gmat-sentence-correction/2841-3-scs-during-recession-federal-government-ch.html and the other E :) http://www.www.urch.com/forums/gmat-sentence-correction/19048-good-one.html As far as your query about C is considered i think that refers to overtime and its not the overtime whoich is the cause but the entire act hence we use the word practice to summarise Quote Link to comment Share on other sites More sharing options...

mitzi Posted March 2, 2009 Share Posted March 2, 2009 Following the destruction of the space shuttle Challenger, investigators concluded that many key people employed by the National Aeronautics and Space Administration and its contractors work an excessive amount of overtime, a practice (it provides a noun) that can, potentially, cause errors in judgment. D is incorrect because of the use of present perfect tense and causing. Have I missed "present perfect" in D)? It seems a simple present tense. :hmm: Quote Link to comment Share on other sites More sharing options...
