Passage Generation

Given a Wikipedia article, in this case one about metal detectors, generate a one paragraph reading passage:

금속탐지기는 전자기유도 및 맴돌이 전류를 이용해 금속을 감지하는 도구로, 19세기 말 광산 개발용으로 최초 개발되었으며, 알렉산더 그레이엄 벨이 대통령 제임스 A. 가필드의 암살 시도 후 남은 탄환을 찾기 위해 급조한 것으로 알려져 있다. 이후 게르하르트 피셔와 Józef Stanisław Kosacki 등의 개량을 거쳐, 지뢰 탐지, 공항 보안 검색, 고고학 조사, 보물 탐색 등 다양한 분야에서 활용되고 있다. 금속탐지기는 저주파(VLF), 비트 주파수 발진기(BFO), 펄스 유도(PI) 등 여러 기술을 이용하여 작동하며, 현대에는 공항, 법원, 기업체 등 보안이 중요한 곳에서 광범위하게 사용되고 있다.

A metal detector is a tool that detects metals using electromagnetic induction and eddy currents. It was first developed for mine development in the late 19th century, and is known to have been made by Alexander Graham Bell to find bullets left after an assassination attempt on President James A. Garfield. Since then, it has been improved by Gerhard Fischer and Józef Stanisław Kosacki, and is used in various fields such as mine detection, airport security screening, archaeological investigation, and treasure hunting. Metal detectors operate using various technologies such as very low frequency (VLF), beat frequency generator (BFO), and pulse induction (PI), and are widely used in modern times in places where security is important such as airports, courts, and businesses.

Question Generation

Create three reading comprehension questions based on the passage above:

• 금속탐지기가 처음 개발된 목적은 무엇이었나요?
• 알렉산더 그레이엄 벨이 금속탐지기를 급조하게 된 사건의 배경에는 어떤 사건이 있었나요?
• 금속탐지기는 어떤 기술들을 이용하여 작동하며, 현재 어떤 곳에서 주로 사용되고 있나요?
• What was the purpose of the first development of the metal detector? -
• What was the background event that led Alexander Graham Bell to make a makeshift metal detector?
• What technologies do metal detectors use to operate, and where are they mainly used today?

This could be useful for language learning tools, especially when combined with LLM-based grading. See also: Summary of Henkel, Roberts, Hills, and McGrane (2023) - Can LLMs Grade Short-Answer Reading Comprehension Questions?
