Mistakes in the Test

DAH!: There are wrong phrases in there as well
DAH!: "chain Bottomless Trap Hole"
DAH!: You don't "Chain" that.
DAH!: -.-"
Satheios: lol
DAH!: It's a response
Satheios: yeah
DAH!: So either way... that one has no right answer, technically speaking.
Satheios: tell me if you see anything else wrong
Satheios: so i can tell her
DAH!: The one about sangan... technically... didn't specify Battle Positions or that they're sent to grave.
Satheios: yeah... was wondering about that
DAH!: Although it'd follow SEGOC rules of a chain. mandatory first player, mandatory next, optional first, optional next.
DAH!: and resolves backwards
DAH!: so another thing wrong is...
DAH!: "recieve"
DAH!: You could go with either "activate" OR "resolve"
DAH!: so that's inherently deceptive and holds no correct answer
DAH!: On the Black Dragon Collapserpent -> TT -> MST, doesn't specify MST's target, regardless: it will resolve, tt still resolves even if destroyed, black dragon WAS correctly summoned, so it'd get eff.
DAH!: however...
DAH!: "add 1"
DAH!: not "special summon 1"
Satheios: yeah, caught that
DAH!: also...
Satheios: i was tired tho lol
DAH!: Barkion... -.-"
DAH!: that one...
DAH!: -.-"
DAH!: The thing about it is... it was negated, so another trap "can" be activated
DAH!: if it were summon
DAH!: on attacks... it plays out slightly different. and the way it's worded...
DAH!: It'd activate in same chain... and then barkion "can" activate again.
DAH!: since it doesn't say "once per turn"

Tell him I appreciate his concern

80% of this is just cherry picking certain words or phrases to make a question out to be wrong when the reader would more than likely know what happens. e.g. Sangan would have to be sent to the grave for said effect to occur, so the reader can safely assume that Sangan was sent to the grave when it asks which effect would resolve first.
