Question 1 is based on the news report you have just heard.

(1) A device that weighs less than one kilogram is part of a mission that will allow scientists to deliver fourth generation or 4G mobile coverage to the moon in 2019. If successful, the tiny device will provide the moon with its first ever mobile phone network. The lunar network will support high-definition streaming of video and data between the moon and earth. The network is part of a mission to the moon. This is a project with the goal of landing the first privately paid for mission to the moon. The 4G mission is set to launch from Cape Canaveral in the United States on a space X Falcon 9 rocket in 2019. Mission to the moon intends to establish and test the first elements of a communications network on the moon. The scientists working on the project opted to build a 4G rather than a fifth generation or 5G network. (2) This is because fifth generation networks are still in testing and trial phases. This means that a 5G network may not yet be stable enough to work on the moon’s surface.

1. What are scientists planning to do?

解析：C。根据录音前两句可知，科学家们计划于2019年在月球上覆盖第四代或4G移动通信网络，故正确答案为C。B项利用generation和mobile phones作干扰，但录音说的是fourth generation or 4G mobile coverage（第四代或4G移动通信网络），并不是指新一代手机，故B项错误。
