I want to know the answer to the following question:
Where was Ivory exported according to the Periplus of the Erythraean Sea?
All the background I'm provided with is that "The state also established its hegemony over the declining Kingdom of Kush and regularly entered the politics of the kingdoms on the Arabian peninsula, eventually extending its rule over the region with the conquest of the Himyarite Kingdom.". Is that enough to answer the question?
Answer: no
