Which fallacy does the following passage commit?

a. professor fallon has asked us to purchase a coffeemaker for her office.
b. but we shouldn’t do that because next she’ll want a microwave, and then a convection oven.
c. then she’ll want a full-sized refrigerator, a sink with hot and cold water, a dishwasher, and a complete set of expensive china.
d. this will exhaust the budget of our department.

The correct answer is:

Causation fallacy (Oversimplification or exaggeration fallacy)

This fallacy is also known as fallacy of reduction or multiplication

Explanation:

The oversimplification or exaggeration fallacy is used to appeal  the fact that one single act would unchain several consequences of the same type without any cause to link it as a real proof of the possible occurrence. In this case, it is simple a prediction that is not based on any type of fact or scientific evidence to prove that this will certainly happen.

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.        

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
