Swift employment application questions

I have some questions about the Swift employment application as it is poorly crafted:

(1) Have you ever been denied a license, permit or privilege to operate a motor vehicle?
(2) Has your motor vehicle operator's license, permit or privilege ever been suspended or revoked?

What is the difference between these two questions?
I had my license suspended for too many points/speeding tickets 20 years ago.
So the answer to #2 would be yes.
#1 seems to me to be the same question.... If my license has been suspended, I was therefore denied a privilege to operate a motor vehicle.
Why the repetition?
What is #1 asking and is the answer also yes?

(3) Have you ever been stopped while intoxicated?
(4) Have you ever been convicted for driving under the influence of alcohol or drugs?

I was convicted of DWAI - "Driving While Ability Impaired" - that is BAC of .04 - .07, twenty years ago.
So that is not DUI "driving under the influence" - BAC .08+.
I will list the conviction under misdemeanor, but technically the answer to both is no.
How should I answer 3 and 4?

(5) Have you ever been convicted for possession, sale, or use of narcotic drugs?

Narcotic drugs are specifically classified as opiate derivatives (herion etc.)
Marijuana is not a narcotic - but a lot of people use 'narcotic' to describe all illegal drugs.
So a 20 year old pot possession charge should mean answering no.
It will get listed under misdemeanors though.
How should this be answered?

I have no other offenses and haven't had even a speeding ticket in over 14 years.
Will these 20 year old and relatively modest offenses give me problems getting hired?

Thanks for any help and clarification!
