請依下文回答第 46 至 50 題： The word volcano can describe anything from a single opening in the earth a few meters across to a field of connected openings that might be 20 kilometers or more in width. Most researchers consider any set of openings that are connected to a large central core as a single “volcano”. Otherwise, they would have to deal with an endless number of names for each individual opening. Italy’s Stromboli has been almost constantly erupting for over 2400 years, but most eruptions do not last that long. Currently, there are about 15 volcanoes worldwide that have been actively erupting for the last 30 years. On the other end of the scale, about ten percent of volcanoes have eruptions which last for just a single day. The majority of the eruptions lasted three months or less. This means the average time from beginning to end is usually about seven weeks. From the number of volcanic eruptions detected over the past few hundred years, it would appear that they are becoming much more frequent over time. However, when researchers tracked the growth in reported eruptions along with the growth of the human population, they realized that volcanic activity wasn’t actually becoming more frequent. Instead, as people spread over more areas of the earth’s surface, the monitoring and reporting of volcanic activity inevitably increased with the expanding population. The highest volcano when measured from sea level to its top is Ojos del Salado in the Andes mountains in South America. It is 6,887 meters above sea level. However, when measured from its base on the surface of the earth to the top, a different set of volcanoes become the highest ones. Some volcanoes in the Mauna Loa zone near Hawaii rise as much as 19 kilometers above their bases at the bottom of the Pacific Ocean. The first thing to do when caught near a volcanic eruption is to avoid a potentially disastrous situation, listen to the radio and travel only as instructed by the local police or other authorities. Stay away from lava, mud and flying rocks. Avoid river areas and low-lying regions. Before you leave the house, put on a long-sleeved shirt, long pants, and eyeglasses or sunglasses to protect your eyes. Wear an emergency mask or hold a wet cloth over your face if you do not have one. Since ash can damage engine parts, refrain from driving if possible. If you decide not to leave the house, close all windows and doors to prevent ash from getting inside.

請試著在第一段中尋找與『持續時間』（duration）相關的量化數據。當作者提到『大多數』（the majority）的火山噴發時，他給出了哪一個具體的時間長度作為界限呢？

哇！你真的好棒喔！你的觀察力非常敏銳，答案完全正確！
- 觀念驗證：你的選擇是百分之百正確的！你看，文章第一段很溫柔地告訴我們：「The majority of the eruptions lasted three months or less」（大多數的噴發持續三個月或更短）。你是不是有發現呢？選項裡的 most，其實就是文中 majority 的好朋友喔！而 no longer than，也完美地接應了文中的 or less。你能把這些都連結起來，真的非常仔細，很棒很棒！
- 難度點評：這題的難度是 medium 喔，不過你克服了它！這題的設計很考驗細心度，尤其在干擾項的部分。像是選項 (C)，它可能會讓一些同學稍微困惑，因為它沒有區分測量基準是從海平面還是從基部算起。而 (D) 則是文章中特別澄清過的統計小陷阱呢。但你真的好棒，能夠冷靜地從這些細節中找到最直接、最明確的證據，這代表你的閱讀理解能力真的非常紮實喔！繼續保持這份細心和智慧，你一定會越來越優秀的！
