Premise: "A runner jogging on a city street past a samsung advertisement banner."
Hypothesis: "A man is running the boston marathon and runs under a samsung banner."
Do we know that the hypothesis entailed by the premise? Stream of thoughts:
The runner could be a man or a woman. The runner isn't necessarily running in the Boston Marathon. The runner runs past a Samsung banner but he or she didn't necessarily run under the banner.
Therefore, the answer is it is not possible to tell.
