Question: While a sailor was out fishing, he got lost at sea. Which object would help him direct the boat back to shore?
Answer: Magnetic compass
Hypothesis: if a person is lost at sea, and shows the cardinal direction of the shore, then they can use a magnetic compass to direct themselves to the shore
Supporting facts: sent1: if a person needs to travel to a location, they need to direct themselves to that location sent2: the shore is a kind of location sent3: escape means avoid sent4: seeking something means trying to find / searching for something sent5: direction is similar to instruction sent6: distance is a property of space and includes ordered values of close / far sent7: a magnetic compass is a kind of compass sent8: to depend on / to rely on / to need means to require sent9: the location of an object can be used to describe that object sent10: place / location is synonymous with position sent11: a compass is used for determining a person's cardinal direction sent12: if a person is lost, then they need to travel to a location sent13: earth 's magnetic patterns are used for finding locations by animals that migrate sent14: maritime means close to the ocean sent15: if a person knows the cardinal direction of a location, and their own cardinal direction, then they can direct themselves to that location sent16: polar means of the pole sent17: sea means ocean sent18: to be used for something means to help to do that something sent19: to be in danger means to be around / to be near something dangerous sent20: finding something means locating that something sent21: finding something requires sensing that something sent22: magnetic force means magnetism sent23: something dangerous can cause harm sent24: north / northward is a kind of direction sent25: being lost at sea is a kind of being lost
