Someone please answer these questions for me

1. What has rihanna accomplished another than her 1's and other figures?

2. Don't you think that if beyonce or gaga had 5 albums just like rihanna they would have the same number of 1's if not more

3. Tell me why Katy Perry has 5 number 1 singles and only 2 albums? Imagine how much she will have with 5 albums
