question:
How would the universe look without gravity? It would have no planets and no stars. Thats how it looked when it was young. When the universe was young, there was only gas and dust. From this gas and dust, everything we now see was made. How were stars and planets created from just gas and dust? The answer is gravity. The same gravity that holds you down on Earth. The same force that causes your pencil to roll off your desk. The same force that causes it to fall to the floor. The invisible force of gravity caused dust and gas particles to be pulled together. This force is what formed all the objects in our solar system. This force formed the smallest moons. It also formed our Sun. This force caused more than just our solar system to form. It caused all the other solar systems to form. It caused the formation of all the galaxies of the universe. <sep>What does gravity do to the universe?<sep>It forms gas and dust
answer:
No

question:
Roma captain Francesco Totti set a new Serie A scoring record on Saturday as his side demolished Cesena 5-1. Two early goals from the 35-year-old striker saw him reach a total of 211 goals for Roma, which means he has scored more goals for one club than any other player in Serie A history. His tally sees him surpass the previous record of 210 set by the prolific Swedish striker Gunnar Nordahl who played for AC Milan in the 1950s. "It's what I've always wanted, to wear this shirt and beat one record after another," said Totti, AFP reported. "I've overtaken Nordahl and I'm proud of that. Now I'm aiming for Altafini," he added, AFP reported. Brazilian Jose Altafini is the joint third highest scorer (along with Giuseppe Meazza) in Serie A history with 216 goals. Totti's early brace and a goal from Fabio Borini put Roma 3-0 up with only eight minutes played. Juan and Miralem Pjanic added further goals in the second half after CM Eder had pulled a goal back for Cesena on the hour mark. The win lifts Roma to sixth -- although Napoli will overtake them again if they win at Siena on Sunday -- and boosts their chances of qualifying for European football next season. Cesena, however, remain mired in trouble hovering just above the foot of the table in 18th place with 15 points. <sep>After Nordahl, whose record does Francesco want to beat?<sep>The Brazilian
answer:
Yes

question:
It is not enough to describe some objects by their location. We may also need to know its direction. For example, a wind blows a storm over your school. Where is that storm coming from? Where is it going? How can we describe a direction? The most common way is by using a compass. A compass is a device with a floating needle (Figure 2.1). The needle is a small magnet. The needle aligns itself with the Earth's magnetic field. The compass needle always points to magnetic north. If you have a compass and you find north. You can then know any other direction. See the directions, such as east, south, west, etc., on a compass rose. The Earth has two poles. It has a magnetic north pole. It also has a geographic north pole. These two poles are close to each other but not the exact same place. <sep>What device has a needle that is a small magnet?<sep>radio
answer:
No
