Explanation:
To find the attitude, try asking yourself whether the author is positive, negative or neutral to the subject. Then look for the evidence. Here, it is obvious that he thinks that nothing very valuable is learned in school about science and scientific method. He is therefore negative. Eliminate the neutral (A and B) words, and the positive (C), and then decide between D and E. He seems to be expressing contempt rather than mocking. And so E is the best choice.
