Most of the mines that Moradco operates in the province of Velyena have never violated environmental regulations.
Statements
quantifier (most) Most Moradco mines never violated in Velyena enviro regulations
conditional / quantifier (every)
Moradco → violated some gold mine enviro regulation
Evaluate
We're given a Most statement and a conditional All statement. In general, Most statements are only interesting as a starting point if you have two most claims about the same group, because then you can prove some overlap.
given Most A's are B these, Most A's are C
we can infer: B and C overlap at least once
But since there aren't two Most claims, the conditional should automatically command our attention. What does a Must Be True question do with a conditional?
It either chains it together with other conditionals (there aren't any other conditionals in this two claim paragraph), or we apply this conditional to a fact that was provided, usually via the contrapositive.
Does the conditional in the 2nd sentence apply to what's talked about in the 1st sentence? Is there any Overlapping Concept?
Yes, both sentences are talking about whether or not something has violated environmental regulations.
We know that most of M's mines in Velyena have never violated. And we know that all of M's gold mines have violated.
So none of those mines we're talking about in the first sentence are gold mines.
Goal
Since the mines being talked about in the first sentence clearly aren't gold mines, since they have never violated an environmental regulation, we can infer that .
Formally,
Most Moradco's never mines in Velyena violated
+
never → not one of violated Moradco's gold mines -------------------------------------------------
Most Moradco's not one of mines in Velyena Moradco's gold mines
Like most Must Be True questions that test our ability to apply a conditional rule, you have to contrapose the rule to see how the available fact(s) triggers it.
