Explanation:
Given that the manager wants to know the type of vegetarian dishes that the people prefer, the sample that is going to provide him with the most accurate data is:
- a random group of 40 people on the street
The reason for this is because this sample has the most number and the people that are used for the sampling were chosen randomly.
A random sampling is very good because it provides an opportunity for every member of a population to be selected.

The exercise is related to the Ratio Test for Convergence. The rules for this kind of test are given below.
<h3>What are the rules for Ratio Test for Convergence?</h3>
The rules are:
- If the limit is less than 1 when conducting the ratio test, your series is definitely convergent.
- The test is inconclusive if the limit is equal to 1.
- The series is divergent if the limit is greater than 1.
Using this knowledge, we are able to state that
- A is not conclusive.
- C's convergence is absolute.
- There is divergence with D and E.
- B and F appear to be employing the nth-term test. The nth-term involves determining the sequence's limit as it approaches infinity.
The nth-term test determines whether a series is divergent if the limit is bigger than 0, thus, both B and F are divergent series.
