Answer: Poor Communication
Dishonesty
Explanation:
1. Poor communication: Communication is vital in every relationship. The way people communicate in their relationship has either a negative or positive effect on the relationship. One of the main contributor to a detrimental relationship is poor communication.
When there's a communication breakdown, this will result into argument, low self esteem, hatred for each other etc.
2. Dishonesty: In every relationship, honesty is paramount. One should be honest in their relationships. Dishonesty brings about lack of trust and this is bad for the relationship. It's important to be transparent. Don't keep secrets from each other.
I belive the answer to the first one is no I would have to assume a habitual zone is one area on a planet. for example, an air conditioned building vs. the Savvanah dessert. However I am not sure maybe other answers will help more on this one. Sorry.... Earth-like planet would of course need water, plant life, animals, oxygen, fossil fuels etc. A challenge we would face on a travel to another liveable planet: do we have engough transportation? engough fuel to make it? How long can we live on this planet? Who or what else is present here? etc. Yes I do think they should discover a planet with earth like qualities befor investing in tools to get us to them. So money is not wasted. (make sure to put this into your own words )
