IV. Read the following passage and decide whether each of the statements is TRUE or FALSE.
A university in Ho Chi Minh City is working on a rescue robot. It is designed to be able to fly to an intended area. It can also dig to get under the ground and find people. Then it sends information about the location of victims and their states to the controller. This valuable information makes the rescue effective. Because it is just the size of a small book, it requires little energy. Its battery allows it to do rescue work in 48 hours.
