Hurting Eyes<br>I got a new job in an office. I worked on the computer all day. This caused my eyes to hurt badly. My mother bought me shades to wear while at work. Now my eyes would not hurt from the computer screen.
The shades were helpful to the person in the story.
Their eyes hurt before they used them, and they don't hurt after they used them. Therefore, the shades were helpful. It's difficult I suppose because this is not stated explicitly and has to be inferred from multiple sentences in the text.
( z1 helpful :ARG0 ( z2 shade ) :ARG2 ( z3 person :location ( z4 story ) ) )
