antigenic shift

[vivek1110]

Antigenic shift refers to the combination of two different strains of influenza; in contrast, antigenic drift refers to the natural mutation of a single strain of influenza.

A influenza; in contrast, antigenic drift refers to the natural mutation of a single strain of influenza

B influenza, different than the natural mutation of a single strain, known as antigenic drift

C influenza, in contrast to the natural mutation of a single strain, known as antigenic drift

D influenza, different than antigenic drift, which refers to the natural mutation of a single strain of influenza

E influenza; in contrast to antigenic drift, which refers to the natural mutation of a single strain of influenza

[spoiler]Can someone please explain why E is wrong?

OA A[/spoiler]

IMO A

E does not have parallel structure

Also, remember that after a semicolon, a complete sentence is needed!!!

I have seen the structures " ; however, NOUN..." OR "influenza; in contrast, antigenic drift" etc preferable over "; clause"

Is this correct, if yes..Why so?

How does a sentence that begins with "in contrast" count as a complete sentence? In general, after the semicolon, you've got to have a sentence that can stand on its own.

Or am I mistaken?

The sentence is able to stand on its own. There is no rule which states that sentence beginining with "In contrast" cannot stand on it own.

Kevin likes fish. In contrast, Lana can't stand the sight of anything that has once been in the sea.


Here we have two complete sentences. True, the second sentence makes no sense without the first, as there must be a contrast

I was of the opinion that, the second sentence should not be able to depend on the second sentence; I didn't know it could.
Thanks for clearing that up
