choice D contains two VERY fundamental problems.

honestly, if you can't see BOTH of the these errors QUICKLY AND EASILY... you need to think—long and hard—about whether you are setting priorities properly. These are both things that you should see IMMEDIATELY.

• "there have emerged ... a picture"
singular subject, plural verb

• "the patterns of ocean currents and what caused them" (WORSE PARALLELISM)
... versus "the patterns and causes of ocean currents" in other choices (BETTER PARALLELISM)

there is NO reason to look at ANYTHING ELSE in choice D. if your attention goes ANYWHERE except one of these two things... your priorities are badly misaligned with the MAJOR concentrations of GMAT SC.

Thank you for the response, Ron. I could exactly find these two errors and was looking for more. I was trying to juice out more out of this choice somehow. By now, after reading so many of your posts, my mind is trained to look for major errors - SV agreement, parallelism, meaning of the sentence/modifier, antecedent of a pronoun - instead of getting into fine nuances and I see that I get down to a choice in a minute and half easily on 90% of the questions.

Thank you again for all the help.
