Answer:

The main threat to internal validity here is History.

Explanation:

Internal validity refers to how well a research is conducted. Internal validity determines if it's the independent variable (or another factor) that caused or resulted in the change in the dependent variable.

History here alludes to the internal validity threat that refers to events outside of the experimental setting (increase in cigarette taxes) that may affect the dependent variable (smoking cessation).

What are some examples of elastic demand?
lakkis [162]

Answer:

Hello there!

I hope this answer will help you

Explanation:

>> Some examples are:-

1) A good example of elastic demand is housing. There are so many different housing choices. People could live in a townhouse, condo, apartment, or even with friends or family. Because there are so many options, it’s easy for people to not pay more than they want to.

2) Clothing also has elastic demand. True, people have to wear clothes, but there are many choices of what kind of clothing and how much to spend. When some stores offer sales, other stores have to lower their clothing prices to maintain demand. Small stores that can't offer huge discounts go out of business. During the Great Recession, many clothing stores were replaced by second-hand stores that offered quality used clothing at steeply discounted prices.
