Read the following passage and answer the question below. Volcanic eruptions are among the most powerful and awe-inspiring natural phenomena on Earth, formed when molten rock, ash, and gases escape from beneath the planet's crust. Volcanoes typically form along the boundaries of tectonic plates, where immense pressure builds up until it is released explosively or through a slower flow of lava. While eruptions can be devastating, destroying communities and altering landscapes within moments, volcanic activity also plays a crucial role in shaping the Earth's surface and creating fertile soil that supports agriculture in surrounding regions. Scientists monitor active volcanoes closely using seismographs, gas sensors, and satellite imagery to detect early warning signs of an impending eruption, such as increased seismic activity or gas emissions. Despite modern monitoring technology, predicting the exact timing of an eruption remains extremely difficult, which is why many communities near active volcanoes maintain evacuation plans to ensure residents can leave quickly if conditions become dangerous. Question: Which of the following tools is mentioned in the passage as used to monitor volcanic activity?
Difficulty: Hard

Reading Comprehension items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Reading Comprehension so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Reading Comprehension item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
