skywalker7861 Posted December 21, 2008 Share Posted December 21, 2008 As the etched lines on computer memory chips have become thinner and the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have vastly increased. (A) the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have (B) the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has © the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive has (D) their circuits are more complex, the power of both the chips and the electronic devices they drive have (E) their circuits more complex, both the power of the chips and the electronic devices they drive have Quote Link to comment Share on other sites More sharing options...
tamdt197 Posted December 21, 2008 Share Posted December 21, 2008 The answer is D, A wrong because it is missing V after the chips' circuits. B makes the same mistake as A. C wrong at the "has" it must be have because the subject of this sentence is plural D is correct E makes mistake as A&B Quote Link to comment Share on other sites More sharing options...
12rk34 Posted December 21, 2008 Share Posted December 21, 2008 The sentence with correct subject verb agreement may be written as: As the etched lines ....have become thinner and (as) the chips’ circuits (have become) more complex, the power of both the chips and the electronic devices they drive has vastly increased. (A) the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have : 'Both' should be placed after 'power'. The correct expression will be 'the power of both'. : INCORRECT (B) the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has : 'the chips' circuits (have become) more complex' is parallel with 'memory chips have become thinner'. Verb 'has' agrees with 'power'. : CORRECT © the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive has : 'Are ' is unnecessary and grammatically incorrect. 'Both' should follow 'power'. : INCORRECT (D) their circuits are more complex, the power of both the chips and the electronic devices they drive have : 'Are' is grammatically incorrect. 'Have' does not agree with singular subject 'power'. 'Their' has ambiguous referent. : INCORRECT (E) their circuits more complex, both the power of the chips and the electronic devices they drive have : 'Have' does not agree with singular subject 'power'. 'Their' has ambiguous referent. 'Both' should follow 'power'. : INCORRECT :) Quote Link to comment Share on other sites More sharing options...
boston_dream Posted December 21, 2008 Share Posted December 21, 2008 The answer is D, A wrong because it is missing V after the chips' circuits. B makes the same mistake as A. C wrong at the "has" it must be have because the subject of this sentence is plural D is correct E makes mistake as A&B Tam, Look at D again. It violates S-V agreement (The power...have) :) Quote Link to comment Share on other sites More sharing options...
Tirpurari Posted December 21, 2008 Share Posted December 21, 2008 12rk34: nice explaination. IMO B for the same reasoning. Quote Link to comment Share on other sites More sharing options...
