Ellipses Doubt

[er_priyankajolly]

Can you please explain why is the below sentence correct?

A mastadon Carcass , which has been thawed only once and is still fresh , is on display .

Why is it same as
A mastadon Carcass , which has been thawed only once and which is still fresh , is on display .

In which all cases this relative pronoun in implied?

I think the second sentence would be considered grammatically wrong on the account of wordiness. Second WHICH is unnecessary.

Received a PM asking me to respond.

Both are okay. The first one is okay because of parallelism:


A mastadon Carcass, which <has been thawed only once> [and] <is still fresh>, is on display .

The "and" indicates parallelism. The parts of the sentence in <brackets> are the two parallel parts. Both apply equally to the sentence, so the "which" that comes before them applies to both. It isn't necessary to repeat it in the 2nd half of the parallel structure (though you can if you want to).
