1, 3, 4 is the three correct answers.
Step-by-step explanation:
1. The Greeks built the Library of Alexandria is actually true, it was the capital of the ancient land where they decided to built it
3. Alexander The Great had scientists when him when they conquered new land so then the scientists taught new ideas about astronomy
5. Greek philosophers shared ideas about rhetoric and logic to everybody in the conquered lands
