Hi all, <br/><br/>Can anyone tell me the usage of "or" in the following sentence ?<br/><br/>"You must get the approval from A, B or C."<br/><br/>So, my interpretation is that I should get approval from anyone of them. The approval from anyone of them is already adequate.<br/><br/>However, I heard another interpretation is that I should get approval from A first, then get approval from B or C. <br/><br/>So, which interpretation is correct ? Thanks
