How much do you know about Star Trek: Original Series? This category is for trivia questions and answers related to Star Trek: Original Series (Television). Each one is filled with fun facts and interesting information.
1 This is the absolute last line: "Her life could have been as rich as any woman's, if only ... if only."
Answer: Turnabout Intruder

This is one of the awful ones, sorry. Although the premise, mind-body exchange, is interesting, the episode is hopelessly chauvinistic, and the last line reflects it. A sad way for the Original Series' final aired episode to end on June 3, 1969.
    Your options: [ Turnabout Intruder ] [ Return To Tomorrow ] [ Is There In Truth No Beauty ] [ The Menagerie ]

2 In the series' first aired episode, "The Man Trap", although the crew only ever refers to this monster as "the creature" in the episode itself, fans generally call it by the name of the substance which it craved: The ______ Monster.
Answer: Salt

The Salt Monster was analogized in this episode to the Buffalo, the Passenger Pigeon, and the Chameleon. Although her frightening "true form" was never revealed until the very end, she took on many false appearances, chiefly Old Nancy Crater, but also, in order: Young Nancy Crater, Wrigley's Planet girl, crewman Green, Uhura's Swahili fantasy man, and finally Dr. McCoy himself! "The creature leading you a merry chase, Mister Sulu?"
    Your options: [ Sodium ] [ Sugar ] [ Silicon ] [ Salt ]

3 In the episode "Journey To Babel" (season 2, #39) we are introduced to Spock's parents. His father is Sarek of Vulcan and his mother is an Earth woman named Amanda Grayson. Which actress played Spock's mother?
Answer: Jane Wyatt

Nothing had really been mentioned about Mr. Spock's parents to this point in the series. It came as quite a shock to find he has a human mother. If you had shown me a police lineup with ten women and asked me to pick the one I thought was Spock's mother, I am sure Jane Wyatt would've been the last one I would have chosen. Her most well-known TV role was as Margaret Anderson, the mother on "Father Knows Best". (Does that make Betty, Bud and Kathy Spock's step-siblings?)
    Your options: [ Jane Fonda ] [ Jane Curtain ] [ Jane Wyman ] [ Jane Wyatt ]

15 In "The Trouble With Tribbles", Chekov claimed that quadrotriticale was a Russian invention. But from what country could that grain actually be traced?
Answer: Canada

Quadrotriticale was a four-lobed hybrid grain, derived from wheat and rye. It was also the only grain that could be grown on Sherman's Planet, which both the Federation and the Klingons were trying to claim. The origins of the grain came from triticale, which was discovered in Canada in the 20th Century.
FAST FACT: Triticale does exist. The first successful fertile crossing of wheat and rye occured in the 1930s. In 1953, the University of Manitoba began an active triticale breeding program, which continues to this day.

16 Hello. I am Ensign Chekov. I am the navigator on the U.S.S. Enterprise. While Mr. Spock has trained me to be as thorough as possible, I sometimes reveal my pride of my home country of Russia just a little too much. Do you know my first name?
Answer: Pavel

Ensign Pavel Chekov joined the crew of the Enterprise at the beginning of Season 2 of "TOS". Rumors he was put there because the Russians complained were actually initiated by a PR stunt done by Gene Roddenberry himself.
Played by Walter Koenig, Chekov was put on the bridge of the Enterprise because NBC wanted to attract a younger audience to the show by putting a youthful, slightly rebellious "Davey Jones" type character on the show. But, because he had just cut his hair before getting the job, Koenig had to wear a wig for his first few episodes!

17 In "The Enemy Within", what is Scotty doing the first time you can clearly see his finger is missing?
Answer: Operating the Transporter

At the beginning of the episode, as Scotty is preparing to beam up Capt. Kirk, there is a close-up of Scotty's hands working the transporter controls. You can see his right hand at the sliders; he tries to hide it with his thumb, but you plainly see one finger on the sliders, and two behind the thumb. There are other occasions in other episodes in which you see a similar (or even the same) shot.

Kirk and his lot beam down, have a nosey and with the help of Spock's mind-meld strategy, work out that the Horta is attacking people because they are destroying its eggs during their mining. The episode ends with the crew of the Enterprise again managing to find a win-win situation for all parties. The Horta digs the tunnels, the miners mine, and everyone respects the other's space.

Answer: they eliminate the crew's sense of fear by injecting them with tranquillisers

The alien feeds off people's fear, usually women's (because women are more afraid of men, of course...). When the alien tries to terrify the Enterprise crew by threatening to kill them, our team come up with the idea of injecting everyone with a tranquilliser to kill their fear. Kirk comments: "Well, Mr. Spock for the next five or six hours we're going to have the happiest crew in space... of course, we won't get much work done." Unfortunately, it also means he will have no-one to beam back down to the brothel with. Life is hard sometimes.
