Because they didn’t know expect the answers
Face the speaker and maintain eye contact.
Talking to someone while they scan the room, study a computer screen, or gaze out the window is like trying to hit a moving target. How much of the person's divided attention you are actually getting? Fifty percent? Five percent? If the person were your child you might demand, "Look at me when I'm talking to you," but that's not the sort of thing we say to a lover, friend or colleague.
In most Western cultures, eye contact is considered a basic ingredient of effective communication. When we talk, we look each other in the eye. That doesn't mean that you can't carry on a conversation from across the room, or from another room, but if the conversation continues for any length of time, you (or the other person) will get up and move. The desire for better communication pulls you together.
Here, you would need to add the preposition "in."
The sentence should read: My elder sister is really interested in the problems of the environment.
Other prepositions would not make sense and could confuse the reader as to the intended meaning.
Answer:
1) We get to see more of the emotional deterioration of Starbuck in season 2 ep 15. And she’s not having a good time. She’s drinking, she’s staying up late, and she’s not endearing herself to one of the pilots under her command, Kat. This at first leads to verbal jousting over who is the pilot with the most kills, but gradually intensifies as the episode goes on. Starbuck, isn’t on top form. She’s still having recollections of her time back on Caprica, and her promise to go back and save Anders, but she’s denied permission to go back and rescue him. Furthermore, we discover she missed a mission in which a pilot was killed, and then she makes a booze-filled lurch for Apollo. The mental state he’s in, they’re clearly a match made in heaven.
2) Raiders reincarnate so that their past lives are learning experiences. They no longer have to go through a training process and have to learn everything again. They get to go into a different vessel with the same amount of intelligence. This way they never die unless their resurrection ship is destroyed which would be a disadvantage to them.
