Dying of cancer, Janice promises God that she will devote her life to the church if He lets her live. According to Kübler-Ross,
Anarel [89]

Answer:

Bargaining

Explanation:

Elizabeth Kubler-Ross developed a theory according to which people go through 5 different stages in the process of dying and grief:

  1. Denial: First, the person cannot accept the diagnosis from the doctors or can think there is a mistake and that he/she cannot be dying.
  2. Anger: In this stage, the person gets angry, usually at God, and gets upset and often wonders why is this happening to him/her.
  3. Bargaining: During this stage, the person says <u>she would do anything in exchange for not dying, he/she will make promises</u> (go to church, be a better person) to survive. These promises are usually made to God.
  4. Depression: The person accepts that bargaining will not work and will start a process of sadness, starting to recognize the reality of death.
  5. Acceptance: The person has come to terms with the fact that he/she is going to die and starts saying her goodbyes and reviews the life he/she has lived and makes arrangements referring to her/his death.

In this example, Janice is dying of cancer and she promises God that she will devote her life to church if he lets her live. We can see that s<u>he is bargaining and promising something in exchange for not dying</u>. Therefore, we can see that she is exhibiting the response of bargaining.

If one of your tires blows out, you should apply your brakes immediately.<br> a. TRUE<br> b. FALSE
gavmur [86]
This is false!

You should definitely not  immediately break as sudden braking, especially with your tie broken could cause you to loose control of your car, which could be quite dangerous.

You should gently slow down and stop, but you should do it slowly and gently, without loosing control.
