Read the following article and answer the question. Article: Scientists know of more than 1,000 volcanoes on the surface of Venus, Earth's "sister" planet. A big question has been: Are they still active? The scientists say yes. Their evidence for recent volcanic activity on Venus comes from a lava flow in the planet's northern hemisphere. The flow is hotter than the rocks around, which means the lava might still be cooling off. "The flow we studied seems to be very young---it is still warm inside," Nataliya Bondarenko said. Venus is a difficult planet to study from Earth because it is surrounded by thick clouds. Telescopes on Earth can't see through these clouds, so the best information about Venus comes from spacecraft orbiting it. Bondarenko and her colleagues studied the lava flow using data from NASA's Magellan mission. That spacecraft spent four years in orbit around Venus and used radar to make a map of 98 percent of the planet's surface. On October 11th, 1994, the mission ended, and the spacecraft plunged through Venus' heavy cloud cover and crashed onto the planet below. While in orbit, the Magellan craft sent microwaves, which can go through Venus' clouds, to the surface. Microwaves are invisible and can be as long as three feet. These waves are a kind of energy, like light. And like light, they bounce off surfaces. The way the waves bounced off the Venus' surface and back to the craft supplied information that the scientists used to estimate the temperature of various parts of the planet's surface. Bondarenko's team found that the lava flow was hotter than its surroundings---which may mean the lava flow is in the process of cooling. The scientists say the lava flow can't be very old because if it were, it would have cooled off enough that Magellan wouldn't have noticed the difference in microwaves. She adds that the flow appears in a 1978 view of the surface that a craft called the Pioneer Venus Orbiter captured. Question: The best title for the passage may be " _ ". Answer:

OPTIONS:
- Warm lava on Venus
- More volcanic eruptions on Venus
- Venus is just like a big active volcano
- Lava flows are first found on Venus

Answer: Warm lava on Venus

Read the following article and answer the question. Article: TS said that everyone has a changing circle of friends. However, no matter how frequently we renew our phone books, some names always remain. These names remind us of the good times we spent together with our friends. Though we may not see them every day, they will always stay in our hearts. Tom was often called "Big Head" at school because of his extraordinarily large head. He was one of my close friends at primary school. But since graduation, we have been studying in different cities and haven't seen each other for a long time.

I realized that time had changed us outwardly, but our friendship hadn't changed at all. I chatted happily with Tom about our shared experiences in primary school. Then I looked around the small room and saw different faces, both familiar and unfamiliar, but none of them the faces of strangers. The whole party was filled with a warm atmosphere. Everyone was lost in the sweet memories of childhood. They forgot all their present-day stresses and pressures. "Hey, what are you thinking about? Come and get some pizza!" A call from a friend woke me up from my thoughts. I hurried towards the table. "Wait! That biggest piece is mine!" Question: According to the passage, which of the following statements is TRUE? Answer:

OPTIONS:
- Tom has changed a lot since primary school.
- Tom invited the author to the get-together party by email.
