My initials are M.C. and know me please do;
I'm related in essence to many a crew;
My syllables count four,
Same for vowels I'm sure;
Now please decide which are false and are true:
Indeed, I'm known to run...
1) alongside a shore.
2) alongside a leader.
3) on a liquid.
4) on a machine.
Three of these are true, and one is false. Which one?
Note: Let's just say for the sake of this problem that "y" is not considered a vowel here.
I'm a proper noun that most people have heard of. I'm not a person, though.
