The correct answer is The lack of a seaport to trade goods might put the people at an economic disadvantage
Landlocked, inland or inland countries
Thus are known in the 'concert of nations' the 44 countries that have no outlet to the sea. In common, besides geography, poverty, the difficulty of doing trade, expanding its presence in the world, winning markets, etc. In Europe, only five of these countries have managed to get rid of poverty, but three of them have had to take serious risks in their banking systems so that, like the oceans, they attract wealth. We speak of Switzerland, Liechtenstein and Luxembourg. The other two European countries are Austria and San Marino. Africa contributes 16 more; Asia, ten; and South America, two more, Bolivia and Paraguay.
Prime numbers are numbers that are only divisible by 1 and themselves. So, to tell if a number is prime, look at its factors.
19:
1 x 19
29:
1 x 29
39:
1 x 39
3 x 13
So, because 39 has more than one set of factors, it's NOT a prime number.
Answer: unreliability
Explanation: Some of the problems that determine the quality of an experiment are reliability and validity.
Reliability considers the consistency of the experiment. In the example above, the result of the second sample is inconsistent with the result of the first sample, making Watt's research unreliable. That is, it does not reflect the ratings of a larger population. This problem can be solved by increasing the sample size, such that the average ratings are more reflective of a wider audience.
Validity considers the accuracy of the experiment. A lack of reliability of an experiment will likely make the result invalid as well, but this is not always the case.
