******************************
Archaeologists in Assam, India, have rediscovered the ancient Daojali Hading site and found important objects from about 2,700 years ago. This site is in Dima Hasao district and was first studied in the 1960s. For the first time, the team found iron materials at the site. This could mean it is the earliest place in northeast India where people used iron. The items found include stone tools, pottery, and polished arrowheads. These discoveries suggest that people lived in this area long ago, possibly from Austroasiatic-speaking groups. Some tools even show connections with China and Southeast Asia. If testing confirms the age of the iron objects, this discovery could change what we know about the history of metal use in India.

1. A piano. Explanation: In English, “keys” can mean both “metal keys” and “piano keys.” A piano has many keys, but they can’t open locks.
英語では「key」は金属の鍵とピアノの鍵盤の両方を意味します。ピアノにはたくさんの鍵がありますが、鍵穴は開けられません
2. The letter “m”. Explanation: “M” appears once in the word minute, twice in the word moment, and not at all in the phrase a thousand years. アルファベットの “M”。“M” は “minute” に1回、“moment” に2回登場しますが、“a thousand years” には全く登場しません。
