根据短文理解,选择正确答案。

    The percentage of women working in technology has decreased since the 1990s.Women make up only a quarter of all jobs in computer and math professions.I think all girls should learn how to code(编码).Here is why.

    If we want to be part of one of the fastest growing job markets out there,we need to jump on board!Over the last ten years the growth in STEM jobs has been three times faster than that in non-STEM fields.Women will never be able to keep up with men in the professional workplace if we don't join the fastest growing fields.

    Just like hundreds of years ago,people who could read and write controlled the future,and now those who are at home with technology will shape the world we live in.You can use coding in every aspect of your life,even if you don't enter a field that involves coding.You cant use coding to create your own website or to program games.You can animate your YouTube videos,or make graphic designs.Programming is now being used in every profession, including medicine and airplane design.

    You can have fun creating your own website,programming a robot to get the remote for you when you're lying on the couch,photoshop pictures to change the color scheme to something better than the Instagram filters,and so much more.Coding allows you to realize your wildest dream,and create anything you can imagine.Coding allows you to rule the world.

    It's not very hard to learn to code.You could learn to code on YouTube,in the Girls Who Code club;you could take a free course online on Code Academy;you could even just Google how to code.

You learned to read,you learned to drive-now learn to code.
