The provided texts do not include information about Mr. Wormwood or his use of an electric drill on second-hand cars, thus the question cannot be answered based on the given information.
Step-by-step explanation:
The information provided does not directly reference the character Mr. Wormwood or what he uses an electric drill for in relation to second hand cars. Instead, the passages provided seem to be from different texts that discuss other characters and scenarios.
Therefore, it is not possible to answer the student's question about Mr. Wormwood and the electric drill with regard to second-hand cars based on the given excerpts.
