The correct answer is: Only argument I is strong.
Argument I is strong because it is based on the idea that annual examinations can have a negative impact on young students’ natural growth. This is a valid concern, as examinations can be stressful and can take away from time that students could be spending on other activities that are important for their development.
Argument II is weak because it is based on the assumption that students will not study seriously if they are not required to take annual examinations. This is not necessarily true, as there are many other ways to motivate students to study, such as providing them with interesting and challenging material. Additionally, even if students do not study as seriously without annual examinations, this does not necessarily mean that they will not be successful in school or in life.
In conclusion, only argument I is strong. Argument II is weak because it is based on an assumption that is not necessarily true.
