I believe the answer would be D. Your GPA is very important when it comes to scholarships and getting into good colleges.
The crime scheme and suspect are very similar in the pattern meaning it is suspect number 2
1. is a sea turtle
2. is a iguana
3. is a frigate bird
4. is a blue footed bird
5. is a galapagos tortoise
6. is a hammerhead shark
I hope I helped :)
