The writer has not even made an effort to understand the discussion topics as these relate to the prompt question. Hence, he failed to provide an appropriate prompt restatement and opinion response. What happened was he created his own topic and discussion method based solely on a poor understanding of the prompt topic. The discussion instruction was not considered at all. The question was, "which viewpoint do you agree with?". A clear single opinion essay based on a clear opinion choice.
His interpretation response was,
although the first idea is true to some extent, the second seems much more reasonable.
A response that is reserved only for extent essays. Therefore, the prompt deviation that will result in an unrelated response is clear to the examiner. The task accuracy score will be failing.
The student will not pass the test due to the incorrect response presentation, regardless of the minor scores that will be awarded to other sections. The score will not be zero, but it won't be passing either.
Honestly, the writer's English comprehension skills need to be properly developed. At this point that most important scoring aspect is his biggest problem. Rather than Task 2 essays, he should write about general essay topics until his understanding skills improve. Only after that should he even try to with task 2 essays. Learn to understand and write as per English instructions first.
