Read the\u00A0supporting details\u00A0then answer the following question.
Which of the following inventions would Thomas Edison MOST\u00A0likely refuse to invent?

In the passage, Thomas Edison was quoted saying that he was proud that he had never invented weapons to kill; therefore, you can quickly eliminate the sonar system, metal detector, and microwave, as they are not inventions that would be used to kill. Thus, the correct answer would be a grenade, as it is a weapon that would be used to kill.
