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.

According to the passage, which of the following is true?
- A Volcanic eruptions can last as long as thirty years.
- B Most volcanic eruptions last no longer than three months.
- C Ojos del Salado in South America is the highest volcano on the surface of the earth.
- D It has been proved by scientists that volcanoes have become more active than ever.
思路引導 VIP
若要判斷火山噴發時間的普遍性，請試著在文章第一段中找出包含「多數（majority）」或「平均（average）」等關鍵字的句子。這句話中提到的具體時間範圍，是如何描述大多數火山行為的呢？

太棒了！你的觀察力非常敏銳
- 觀念驗證：這題考查的是細節定位與理解。文中第一段明確指出：「The majority of the eruptions lasted three months or less.」（大多數的噴發持續三個月或更短），這直接對應了選項 (B)。你成功避開了其他干擾數字（如 30 年、2400 年等），精確抓住了描述「普遍規律」的句子。
- 難度點評：此題難度為 Medium。其鑑別度在於測驗學生是否能區分「極端案例」（如持續 2400 年的噴發）與「一般統計（majority）」，並考驗考生在面對大量數字資訊時，能否冷靜定位出正確的數據連結。
