Since most of you will ask for the source, I have uploaded an image containing the content itself. If needed, I can add the link to these texts also.
The sentences beginning with "or" confuse me a little. In the first context, does it mean, "he wanted to walk on streets at least until he could see his daughter"?
In the second context, if the first construction is talking about the possibility then the second should also. So, it should say Or a beetle may get picked up..". Doesn't the sentence sound strange with its current construction?
