Hi
GMATNinja,
Could you please explain why "have begun" is correct and "began" is wrong? I read a few explanations, and since I'm not a big fan of jargon, I couldn't really understand the difference. It would be really very helpful if you could explain it with some example
"Have + VERB" suggests an action that started in the past and continues into the present. The construction "Since + YEAR," implies the same -- the action started in the specified year and is ongoing.
Here, have an example:
"The Sacramento Kings have made brilliant personnel decisions since 2003."
Translation: the team started making brilliant decisions in 2003 and they continue to make brilliant decisions today. (Apologies to all seven Kings fans out there.)
In the official example, we're talking about a behavior that's been happening "
since 1986," so the "have" correctly conveys the fact that the behavior has occurred from 1986 through the present.
Put another way, I could write, "
In 1986, several corporations
began," or "
Since 1986, several corporations
have begun."
No jargon necessary! For more low-jargon rambling about verb tenses, check out

I hope that helps!
- other than "since..." -- what other trigger words do you look out for, when thinking about using the present perfect ?
