I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "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."?
A:
The century for the 1st and 2nd century is shortened to what?
