Final answer:
Procrastination is not the MOST obvious deterrent to educational success; factors like social class, excessive television watching, and inadequate learning resources also significantly affect a student's educational outcomes.
Step-by-step explanation:
The statement "The MOST obvious deterrent to educational success is procrastination" is false. While procrastination can certainly hinder educational success, there are numerous other significant factors that can be equally or more impacting. For example, social class greatly influences a student's ability to succeed educationally. Students from lower socioeconomic backgrounds may face multiple challenges such as limited access to resources like adequate study spaces, technology, and support from family.
Another deterrent is the impact of excessive television watching on academic performance. Studies have demonstrated a negative correlation between the number of hours spent watching TV and grades. Specifically, students who watch more television tend to perform more poorly on their exams. It is implied that time spent in front of the TV is time not spent on studying and that the type of content consumed might not be educational.
Furthermore, the lack of educational resources in some rural areas serves as an obstacle. The absence of basic facilities such as desks and chairs can make the learning environment unsuitable, hence impeding students' abilities to complete their school work effectively. Therefore, while procrastination is indeed a barrier to success, it is not the sole or most obvious deterrent, as students' educational achievements are influenced by a complex interplay of factors.
