I am so done with the auto-logouts on this website. Liek so done. No rly. *grumble mumble*
Anyway...
1. Because how else would they have been able to drive it to safety?
2. It is likely that the raptor's communication is instinctual, as they communicated the same exact way in each movie, even though it was a different pack for each movie.
3. What everyone else said. They didn't communicate, they just respected the other enough to not try and kill eachother.
4. So that if it died or they had to transport it, they wouldn't have to call in a helicopter or tear down a wall in order to move it. The better question is why that particular door was open in the first place, as there were many smaller, man-sized entrances into the enclosure, to which the answer is so that the Indominus could escape.
5. Those stun-guns we saw are probably able to take down a T. rex, but the Indominus' literally bulletproof skin was simply to thick for them to do more than cause the monster some minor discomfort. I mean, this is a creature that took several 12 gauge shots from point blank and didn't even flinch. On top of that, it also survived sustained fire from an M134 minigun, a weapon which, mind you, fires 7.62x51mm bullets (which is more than enough to go through a car's engine block!), at a rate of fire anywhere from 33-100 bullets A SECOND.
6. They probably do. We just never saw them because none of the main-characters never had any reason to go to them. And honestly, an emergency shelter isn't the sort of thing you want to have on mainstreet at a theme-park. I mean, imagine if you went to Disney world and the first thing you saw was a bomb-shelter.
7. Did you watch the movie? The Ingen soldiers flew in on several helicopters. On top of that, the park itself almost certainly had more helicopters, and I'd like to say, once again, that just because we didn't see them, doesn't mean they weren't there.
But yeah, apparently when Hammond kept saying that they spared no expense, he was talking about the gasoline in their Jeeps. /s/
