They seem to be asking a lot of technical questions which licensed hams should know.
Your browsers AI search engine should be able to find the answer in case you don't know.
They are reusing some questions from the last time the prize was an ICOM IC-7300 in 2024.
See: https://slickdeals.net/f/17467908-gigaparts-yaesu-icom-ic-7300-august-8-2024-fcc-licensed-us-amateur-operators-only?t=17467908
I encourage you to post both the question and the answer and not just the answer..
Historically, GigaParts has repeated the same questions from one sweepstakes in later ones.
If you post the question, then in a later sweepstakes when they repeat the question you can do a
keyword search of the previous thread and quickly find the answer.

What is the approximate Q of a parallel RLC circuit at resonance if R = 47 kilohms, L = 10 mH, and C = 100 pF?
Answer: I don't know
Entry page https://www.gigaparts.n
The correct answer is 4.7 which is not offered, I picked 470 figuring GigaParts misplaced the decimal point somewhere in their calculation but that was marked incorrect. Of the four answers offered:
Approx 235
Approx 470
Approx 700
Approx 940
all are incorrect.
Let's do the math:
Q = R times the square root of the ratio of C over L.
Calculate the ratio C/L
10mH = 0.01 H = 10 to the minus 2nd power Henry
100pf = 10 to the minus tenth power Farad
The ratio of C/L = ten to minus eighth power
Take the square root of the ratio C/L = ten to minus fourth power
Multiply that by R. 47000 x ten to minus fourth power = 4.7.
Interestingly some on line calculators give the correct answer 4.7 and some wrong ones.
