There is a photographer who takes photos and searches for pictures on the homepage of homework help. You can choose any subject you need.

After the search is completed, the mobile phone page will automatically display the answers, and sometimes there may be some matching problems, so slide the page to the right. You can see more similar questions and answers. If you want to change the question, click the Modify Question button to the right of the topic.

I don't know what the specific solution is. Click ask the teacher at the bottom.
