Dec 4, 2018 at 21:29	comment	added	aglearner		Dean, my original question was more general, and John immediately gave a counterexample, which illustrates that vanishing of the Euler class doesn't guarantee existence of a non-vanishing section. However, since I really want the answer to my question above (about submanifolds of $\mathbb R^n$), I decided to modify the original question. So now John's answer doesn't answer the current question, but it nicely illustrates it.

Dec 4, 2018 at 12:24	comment	added	aglearner		Thank you John. I edited the question, because I do want to know the answer to a part of the original question, which was not covered in the previous question on mathoverflow.
