Summary
Most mines that Moradco operates in the province of Velyena have never violated environmental regulations. Every gold mine Moradco operates has at some time violated environmental regulations.

Notable Valid Inferences
Most of the mines Moradco operates in Velyena are not gold mines.
A
Moradco operates more mines in Velyena than any other company operates there.
Could be false. We don’t have any information in the stimulus about the total number of mines to make this comparison. Our conditions are restricted to the proportion of mines that have or have not violated environmental regulations.
B
The total number of gold mines that Moradco operates is larger than the total number of mines it operates in Velyena.
Could be false. We don’t have any information in the stimulus about the total number of mines to make this comparison. Our conditions are restricted to the proportion of mines that have or have not violated environmental regulations.
C
Most of the gold mines that Moradco operates are not located in Velyena.
Could be false. We don’t have any information in the stimulus about the total number of mines Moradco operates to make this statement. We cannot assume that just because most mines in Velyena have not violated environmental regulations that most mines are not located there.
D
Most of the mines that Moradco operates in Velyena are not gold mines.
Must be true. As shown below, we can take the contrapositive of the last statement in the stimulus which tells us that if a mine has never violated environmental regulations, then that mine is not a gold mine.

E
Most of the mines that Moradco operates throughout the world are not gold mines.
Could be false. We don’t have any information in the stimulus about the number of mines Moradco operates outside of the province of Velyena. It is possible that most of Moradco’s mines are in Velyena.
