conclusion

One evening my sister, Jane, and her husband were entertaining guest while their kids did their homework upstairs. During dinner, eight-year-old Jeff appered at the table. "Mum," he whispered trying not to be noticed.

"What is it, honey?"

"I need some help with my science experiment," he sad, handing Jane a marker and a piece of paper.

"What's this for?"

I need to draw a conclusion," Jeff said seriously, "but I don't know what one looks like."
