the answer is: <span>the third variable problem
</span><span>the third variable problem refers to the additional factor that could mistakenly lead to the false conclusion in determining the causal relationship between two other factors.
Other example:
There was a study that shown that eating soy bean leads to the development of breast cancer. But if we take a look at East Asian population who consume more soy beans compared to western people, East Asian population have far less cancer cases.
In this case, we can say that Genetic is a t</span>hird variable problem

Answer:
Answer is incurable economic obsolescence.
Explanation:
An incurable economic obsolescence is a situation whereby the value of benefit of a thing is less compared to the cost .
For example, when a big factory is being established in an area where people are residing or area planned to be a residential area will loss its value, because people will not want to live in an area where a factory is located. This will eventually drive the residents away and prevent future land buyers to buy from the area.
In the case highlighted in the question, the value of the building is depreciating and this will prevent people to rent the house from the homeowners, and people will buy at very low price if they are planning to sell the houses.
Answer with Explanation:
Overt and Covert research methods are both used in <em>observing subjects.</em> The main difference relies on the "awareness" of the <em>subjects/participants</em> being studied.
In an overt research method, the subjects are <u>aware</u> that they are participating in the study while in a covert research method, the subjects are <u>unaware.</u>
The advantages of overt research method is that the participants have <em>informed consent.</em> So, whatever happens is not the fault of the researcher. Since the participants are aware, it becomes easier for the researcher to record events in their presence. On the contrary, it brings about some disadvantages. Since the participants know that they are being observed, they may be<em> inclined to change their behavior.</em> This is called the "Hawthorne Effect." This affects the validity of the outcome of the research.
The advantages of the covert research method is its <u>more valid outcome of research.</u> The participants are <em>naturally behaving,</em> which means that it is more valid as a method than the overt. It is also easier to access closed groups because they are unaware you are observing them. However, one disadvantage is the "deception" it needs to tackle as it <em>doesn't ask informed consen</em>t from its subjects. This has always raised ethical concern, especially for people who value their privacy.
So, this explains the answer.
