Eric's Mistake<br>Eric was going on a road trip to Harper's Ferry. He set his GPS to the route, but the battery died part way through. Eric ended up making several wrong turns and getting very lost. Eric refused to ask for directions and ran out of gas. Eric had to walk 5 miles to a gas station to get more gas.
Eric's dead GPS battery was the sole reason he ran out of gas.
System apparently recognized the phrase "dead battery", but didn't catch "sole" cause.
