My guess:
(d) – the others are Big Mac ingredients, as per the jingle
One possibility:
(c) – Kutch is in India, the others are in Pakistan
How about
(c) – each of the others is attributed to one man (Paine for the first and last, Kennedy for Profiles, while The Federalist Papers are generally considered to be the joint effort of Hamilton, Madison, and Jay
Can it be this easy?
(c) – the others are characters in Beetle Bailey
Sternvogel, you got two of them right: 22 and 29.
As for the others:
21. Hyoid is a bone; the others are cranial nerves.
23. Dir is a state in India; the others are parts of Pakistan.
24. Beria was never head of state of the USSR.
25. Escutcheon is not part of a cowboy’s riding gear.
26. Profiles in Courage was not written in the late 18th Century.
27. Vera Miles was alone and apprehensive in Psycho; the others refer to Cary Grant in North by Northwest.

30. Turmeric is not ordinarily put on a hot dog.

C. Sirica was the only non Watergate conspirator. He was the judge who tried the case IIRC
C. a board is not a simple machine
C. Elmo Zumwalt was in the navy. The others were in the army
I can think of two possibilities.[spoiler]Baffin could be the odd one out, because the others are all in the tropics and Baffin Island is in arctic Canada.
Or it could be Exuma. The others are all individual islands, but Exuma is a region of the Bahamas consisting of many islands (the largest of which is Great Exuma Island).
Odd that you would mention Exuma. I’d never heard of it, until I flew there about a week ago in Flight Simulator.[/spoiler]

29 © This was not a Broadway musical.
I’m sorry, but this is terrible. Elvira Madigan was Danish tight-rope walker, about whom a movie was made in 1967, which prominently included Mozart’s Piano Concerto in C major, K. 467 in its soundtrack.
Elivra Madigan is not “by” Mozart in any reasonable sense. You could say it’s a movie by Bo Widerberg, and speak of the “theme from Elvira Madigan,” which is from the Mozart Concerto mentioned above, but that’s it.
Oh, all right. :rolleyes:
I have a cassette of Mozart music which includes that piece but the liner notes don’t go into that much detail.
I hope not…

c) Bill Russell played basketball - the others are baseball players
Back on #1, my first guess was Jughead, as he was the only one not known by his real name (which is Forsythe, believe it or not).
However,
the Dodgers had a shortstop named Bill Russell (white guy, so definitely not the Celtics star). Yeager was a catcher for the Dodgers, while Lopes played second base for L.A. Woodling was most notably a New York Yankee, so that’s my guess.
Right, Sternvogel. 
The Dodgers mentioned were from the Big Blue Wrecking Crew of the mid-70s. Woodling played in the 50s.

d) Broadloom
a) Ben Turpin
b) Groucho Marx
c) Buster Keaton
d) Chester Conklin
d. Broadloom is the odd one out. There others are all types of sails on a sailboat or ship. (In the nautical tradition of dropping letters and syllables whenever possible, I’ve usually seen topgallant as “t’gallant”.)There’s no way you were gonna get this one past me.
That reminds me of a Navy cartoon in the *New Yorker *during World War II. A sailor is writing a letter and asks his bunkmate, “How many apostrophes in ‘fo’c’sle’?”
I’ve been in a fo’c’sle, and I’ve braced a t’gallant.
Omaha Beach was a World War ii site, while the other places were affiliated with the Vietnam conflict.
Buster Keaton was not known for wearing a mustache.
