Is the usage have offered correct.......
Plas help me negate D

D. have offered the most dramatic evidence of the close evolutionary relationship between dinosaurs and birds that have yet been discovered

NO you don't need Present Perfect tense here.

Another problem with D is Relationship needs HAS not HAVE.

So D is a bad option. BAD BAD BAD!

And A is the winner.

Another problem with D is Relationship needs HAS not HAVE.

full verb is : HAVE OFFERED which means they started to offer in the past and they still do

Yes fossilS are plural and OFFER is perfectly fine and A uses the simple present tense.

logitech i would really appreciate if you can help me out on this!!


present perfect ---> action started in past and continues in the present

i get confused sometimes regarding the continuity of the action,,

feathered dinosaurs offer the most dramatic evidence..



1995-- Discovered : offer evidence


2009--- now: today also the evidence is there...

so why can't i use the present participle tense.......

d) have offered the most dramatic evidence of the close evolutionary relationship between dinosaurs and birds that have yet been discovered

Can we eliminate "d" on the basis that it says birds and dinosaurs that have yet been discovered...whereas the original sentence says evidence that yet have been discovered. So it is changing the meaning.

Not really

relationship between dinosaurs and birds that have yet been discovered

Thats the noun which is being modified, and also please note that HAVE needs be HAS

yes, in that case modifier should be next to the noun it is modifying. If it wants to modify then it should be adjacent to relationship.

"relationship between dinosaurs and birds that have yet been discovered "

Also IMO relationship exists and not discovered. This sentence to me looks very awkward.

Even if we say relationship is discovered, then also IMO better and clearer would have been

"relationship that have yet been discovered between dinosaurs and birds "

Even I am also confused between A and D..

Can somebdy please help..??

sungoal wrote:Even I am also confused between A and D..

IMO A

We can eliminate D and E : seeing have offered only.

An event which is independent from the time : a simple present is preferred.

Here
A :
fossils of feathered dinosaurs offer : simple present

Some general statements. There are times in a sentence when you could choose to use either present or present perfect. goel is right that D indicates that the dinosaurs and birds are somehow being modified by the "that have yet been discovered," which does unacceptably muddle the meaning. Or, logitech, if you want to say that the "have yet been discovered" modifies relationship, that also is the wrong thing. So, either way, the words no longer indicate the right meaning: that we're talking about the most dramatic evidence that has been discovered.

My views:

Unearthed in China, fossils of feathered dinosaurs offer the most dramatic evidence yet discovered of the close evolutionary relationship between dinosaurs and birds.

A. offer the most dramatic evidence yet discovered of the close evolutionary relationship between dinosaurs and birds

Could not find anything wrong

B. offer evidence more dramatic than what has yet been discovered of the close evolutionary relationship between dinosaurs and birds

Many issues:
(1) MORE DRAMATIC is wrong as we are talking about all discoveries made till yet. MOST DRAMATIC required
(2) what has yet been discovered - VERY WORDY

C. offer more dramatic evidence of the close evolutionary relationship than any yet discovered between dinosaurs and birds

Many issues:
(1) MORE DRAMATIC is wrong as we are talking about all discoveries made till yet. MOST DRAMATIC required
(2) the modifier "between dinosaurs and birds" should be closer to RELATIONSHIP
(3) what does ANY modifies (RELATIONSHIP OR EVIDENCE) - not clear

D. have offered the most dramatic evidence of the close evolutionary relationship between dinosaurs and birds that have yet been discovered

(1) HAVE YET DISCOVERED modifies "dinosaurs and birds"
(2) comparison between EVIDENCES not clear

E. have offered more dramatic evidence than any that has yet been discovered of the close evolutionary relationship between dinosaurs and birds

MORE DRAMATIC is wrong as we are talking about all discoveries made till yet. MOST DRAMATIC required

IMO A
