This should be easy to understand, now let's move on to 2B.
___________________________________________________________________Important Note:
If you have been reading my previous entry on Zero & First Conditionals, you would have realised 3 things:
Tenses Used: From Present to Past
Time Concern: From "anytime" to only "future and present" --> moving back in time gradually.
Chances for condition to happen: From 100% possible to 100% impossible.
This is the trend for conditional sentences. In the future, you can expect that the Third Conditional would follow this trend too. Till then, enjoy learning!
PS: I hope you enjoyed my examples. I have tried my best to make it sound ridiculous.

Apart from the movie "Stuck On You" by Matt Damon and Greg Kinnear, I haven't really seen any other movies which talk about conjoined twins, nor do I know of any others.
There is another term for conjoined twins, commonly used in the movie, called "Siamese Twins", originated from the most famous circus pair of Chang and Eng Bunker in Siam (now Thailand). Of Medical term, this is a form of "Omphalopagus", sharing their liver.
After watching an episode of House on TV one time "Cane and Able", I discovered that there is more to just twins connected through the body. The episode talked about a boy who kept seeing aliens and imagining he was always being captured by them. This boy is so special that he carries two types of DNA strands in his blood. Dr House later figured out that the boy was a chimera, an example of Chimerism (a form of Genetic Mosaicism), of which he actually had a twin brother growing inside his brain in the form of a tissue and was controlling the imagination of aliens. After removing this tissue (his brother), the boy was back to normal.
In an episode of South Park, the school nurse Gollum happened to be suffering from a ficitional diseases Conjoined Twins Myslexia (You can watch this episode by clicking on the link), I suppose this is a form of "Craniopagus".
