YOU ARE CORRECT!
Here are the explanations...
1. What you saw was not really what you saw... The ambassador tells Riker they have seen humans eat meat, but Riker explains that what the delegates saw was something as tasty and looks like meat, but it is replicated.
2. One letter away from home... Picard uses the letter 'P' to give the signal to come home.
3. A hobby begins here... Data starts his fascination of Sherlock Holmes here.
4. A one time used device... We only see the headpiece Crusher wore in this episode. (Troi's device works, also.)
5. A first for TNG... Singh has the dubious honor of being the first death on the Enterprise-D.
6. Senior officers are included... Geordi says it's not just the junior officers Picard has learn everything.
7. Two in one... When under hypnosis, Crusher describes being as if two are in the same body.
8. A planet named after a government... Parliament is where they are going.
9. A shocking experience... Self explanatory.
10. Second appearance of this character, but first time wearing this... O'Brien appears here for the second time, but it's the first wearing the gold.
Your turn, LeadHead.
