C is most concise. Although E is grammatically correct, introduction of relative pronoun "that", along with present perfect tense, makes it wordier
May be I am missing something here, but I will explain why I chose E.
1) A and C are the same, except for word re-arrangment.
C = An effort
begun two years ago to upgrade the health care of children
is starting to save lives in dramatic numbers, according to the executive board of the United Nations Children's fund
I think there are two verbs here for the effort - begun and is starting - and may hence be a run on sentence like all the other three.2)
E = An effort
that has begun two years ago to upgrade the health care of children is starting to save lives in dramatic numbers, according to the executive board of the United Nations Children's fund.
that has begun two years ago - is the relative clause - we removed the double-verb error by sending one verb into the relative clause. NEWKID
Hardworker Indian,
Quote:
'has' is okay, I think. Use has for anything that started in the past, where a clear time of occurence is not known.
Apparently the effort has begun in the past, so they call it "has begun". There is even a clear hint on time - "two years ago".
"An effort that has begun two years ago.
If the sentence was " an effort
that began two years ago"...Would that have been correct?
I will modify my explanation from the above quote:
Use present perfect (Eg: 'has begun') for anything that started in the past, and may continue to happen in the present.
Use past (began) for anything that happened in the past
