Agree or Disagree

1.) The weather and your surrounding affects your mood.
Agree.
Weather can affect your mood. If you live in a congested city that's gloomy all year round, you're bound to dim. People need light, it brings happiness, and warmth. Sun draws you outside to explore your environment and socialize. Your mind also creates its own opinion which is imprinted there until you decide to change it. Your environment also changes your mood. You have to be somewhere you are content. For example in Fahrenheit 451 the social situation is such that you're not allowed to be happy to the people are brainwashed into living a dull city to robotically go about their daily routine.

2) It is difficult to go without food for a whole day.
Disagree.
Many people in Africa don't eat for days or eat extremely little amounts. It is all in your mind if you constantly think about eating, it will increase your desire to. For example at school we had a 30 hour famine, during which students fasted or if necessary had a small portion of rice. There were various activities set up, such as soaking the former principal, which took their mind off the task in hand. It especially can be done with a little help from your friends and some fun.

3) Going through a difficult time can make a person more mature or give them more confidence.
Agree and disagree.
Going through or experiencing a rough patch can crush a person's self-esteem. For example if you loose a loved one you were close to, it doesn't make you more confident, you're in mourning. In most cases tough times leave scars that take a long time to heal.
Yes they become more mature because they have to learn to deal with certain things you normally wouldn't think about or even take for granted, like having a family member around or a close friend. You don't have time to mess around, but instead have to comfort and support each other in order to try and get through the hard time.

4) The love of the money is the root of all evil.
Agree.
Greed pushes people to do thing they wouldn't normally do. For example Hitler, greed ended up being his biggest downfall, when he was lead into the coldest part of Russia and froze all because he wanted the whole world to be his. The amount of lives he took was irrelevant, simply a number to him. Most wars are based on greed, is it really worth it? When you gain in power the greed becomes more and more, you start taking greater risks or putting other people in danger. The love of money can control a person, influence the way they think, just be happy and thankful with what you have, extras are a bonus.
