Question

When these policies and guidelines are strictly observed, the advantages of Tasers maximized and their shortcomings are all but eliminated.

Should are be taken out of the sentence? or should it be were all but eliminated?

Answer 1

You need to add "...<I>are</I> maximized, and their...."

Or you could revise it one of these ways:

When these policies and guidelines are strictly observed, the shortcomings of Tasers are all but eliminated.

When these policies and guidelines are strictly observed, the shortcomings of Tasers are minimized.

I hope this helps. Thanks for asking.

I think it's:

When these policies and guidelines are strictly observed, the advantages of Tasers maximized and their shortcomings nearly eliminated.

Am I correct?

Answer 3
