Please answer the following question: I know that the answer to the question "what route is mentioned first?" is in "The Silk Road transmission of Buddhism to China is most commonly thought to have started in the late 2nd or the 1st century CE, though the literary sources are all open to question.[note 41] The first documented translation efforts by foreign Buddhist monks in China were in the 2nd century CE, probably as a consequence of the expansion of the Kushan Empire into the Chinese territory of the Tarim Basin.". Can you tell me what it is?
Answer:
The Silk Road
