text: Another reason Venus should not be considered dangerous is becase of the technology they can use to see if it is ok for people to be there. In the 1800s they used to use mechanical computers. This device could do calculations. In the passage in paragraph 7 it says " These devices make calculations by using gears and levers and do not require electronics at all." This is showing that technology can help people see if the planet is dangerous or not by using the power and flexible and quick power it has.
