Can we draw the following hypothesis from the context (see options)? 

Context:

We present a novel approach to enhance avalanche companion rescue using wearable sensing technologies. The time to find and extricate victims is most crucial: once buried by an avalanche, survival chances drop dramatically already after the first 15 minutes.

Hypothesis: After a quarter of an hour people are more likely to die when in an avalanche
OPTIONS:
+ Yes.
+ It's impossible to say.
+ No.
Yes
