16.=D.
17.=1.
18.=Please show the last option!
When you are a child, if you grow up in an abusive household, you learn to be more aggressive. However, if you have a loving household, you're more likely to be considerate of others. There are many other examples, such as someone smiling to you could save your life, while someone being rude could end it. It only takes one gesture to change someone's world.
The answer should be D
good luck :)
