Give one example of when you would make a frequency table to solve a problem

Frequency shows how often a value in a dataset occurs. If five students have the score 75 from the exam, it means the frequency is five. By arranging values in an ascending order with their corresponding frequencies, we obtain a frequency table.
For Example:
 
20 students in a class got the following grades out of 10:

6 7 5 7 7 8 7 6 9 7 4 10 6 8 8 9 5 6 4 8

How can we construct a frequency table according to this information? Solution:

In order to construct a table, first, we write the numbers in ascending order: 4 5 6 7 8 9 10 In the next step, we write the frequencies of these grades and the final answer is going to look like as:

                                       Grades              Frequency
                                            4                        2
                                            5                        2
                                            6                        4 
                                            7                        5
                                            8                        4
                                            9                        2
                                            10                       1

They sought new allies to germany tried to get mexico to join and put pressure on the us. the us joined the allies because of the lucitania

I'm just guessing, but my answer would c. 0 to 300.
