　　A Google-backed project to bring internet connectivity to rural areas around the world is set to launch its first service in Kenya. The project is led by Loon, which is owned by Google's parent company, Alphabet. Large balloons carry solar-powered equipment high in the sky to send high-speed internet signals to the ground. Loon officials told that its balloons are expected to reach Kenya in the coming weeks. Loon began testing the system in 2011,
but this is the company's first market test. The service will sell 4G internet service to people living in a rural, mountainous area. Kenyan transportation officials said they expect to give final approval to the project this month. It is made of a plastic material that is built to last at least 100 days. The balloons are filled with gas that is lighter than air and rise up to 20 kilometers into the sky – a height twice as high as airplanes fly. This helps the balloons avoid weather problems and wildlife.
Loon balloons move through the skies by wind currents that carry them up and down during the flight path. They are designed to link up with a team of balloons over areas lacking internet connectivity. Stations on the ground send signals from local internet service providers up to the balloons. These signals are then fed back to earth in a similar way to how satellites work. People on the ground can then connect to the high-speed internet service. Loon says solar collectors power the equipment during the day and charge a battery to run the system at night.
　　Question 1: According to the news report, what kind service would the Google-backed project Loon provide in Kenya?
