Answer:
Thematic statement: Participating in sports is a great benefit for the body, but this practice should not interfere with other important elements such as education and physical capacity.
Rhetorical strategy with logos: If being an athlete impairs academic performance, or if the practice of exercise is causing some harm to the body, the sport is not beneficial but harmful.
Explanation:
In "The Proper Place for Sports," Roosevelt argues about his son's desire to join the school's football team. In the letter Roosevelt is concerned that the boy's physical condition is sufficient for the sport he wants to practice. However, Roosevelt agrees to let him take the test if the coach says he is not in danger of health. Roosevelt also says that playing sports is very important, but this should not be done to the detriment of the academic performance of the boy, who must maintain good grades and be concerned with studies.
Accordingly, we can say that Roosevelt is in accordance with the thematic statement and rhetorical strategy shown above. He agrees that if sport is damaging the body and academic performance, sport is not being beneficial and, therefore, losing its main function.
The correct answer is "Group II. When the root is a full word except for a final e, the forms usually are spelled with -able"
Explanation:
The passage presented in the question explains the basic rules for adding the suffix "-able" to a root word or basic unit that forms words, for doing this, there are eight different rules that define the correct way to add this suffix mainly based on the features of a word. In the case of the word "desire" this word is a root by itself which means it cannot be reduced to smaller particles and this word ends in "-e", also the correct form of adding the suffix "-able" is in the form "desirable" which means the final "e-" is omitted and the suffix is added. Therefore, this word belongs to the rule "Group II", because as desire words of this group are full words excerpt by the "-e" that need to be omitted to add the prefix.
It is necessary because if you don't have a confirmed opinion with textual evidence to back it up you wont have a good argument.
