What type of cause is described in each of the causal descriptions given below? Is it (a) necessary condition, (b) sufficient condition, (c) necessary and sufficient condition, (d) proximate or triggering condition, (e) controllable condition, (f) background or standing condition? In some cases, more than one answer is correct, but you need only give one. 17. Lack of oxygen in the chamber caused the death of the mice in the experiment. 18. The Titanic was sunk by having its hull ruptured by an iceberg below the waterline. 19. Ashley’s symptoms have not improved because the dosage of her medicine is probably too low. 20. An organism is conscious if and only if it has a central nervous system.

1. A. Necessary condition.

According to its definition, if an organism does not have oxygen it dies, so the necessary condition becomes vital and without it life does not occur.

2. F. Fund condition.

With the information we can see that so that in a system like the ship it ceases to be viable and useful, a part was divided and that led to its destruction.

3. C. Necessary and sufficient condition.

With the clinical case, we observed that there was a problem in the patient but it was resolved thanks to a medication effect, which, being effective, disappeared the problem and did not require other interventions.

4. D. Proximate and triggering condition.

There is talk of the need for the nervous system for the body to have consciousness, which makes it a factor that produces an effect and is required for it to occur.
