Julia is eating a pear.

　　Julia: This new genetically modified (GM) food tastes different from before.

　　Sergio: I suppose so. It is really hard to know the difference.

　　Julia: I can tell.

　　Sergio: How?

　　Julia: I can taste it. Natural fruit tastes sweeter than GM fruit. The natural product is also not so perfect.

　　Sergio: That's because the insects get at it. Scientists have been modifying food for some time. Just think about the seedless watermelon. How did a watermelon get seedless?

　　Julia: I forgot about that.

　　Sergio: There is probably much more than you or I realize. It just takes time to get adjusted to it. One thing I can't figure out though?

　　Julia: What's that?

　　Sergio: How do you grow seedless watermelons? I mean, if you need a seed to grow fruit then how do you grow new watermelons if you don't have a seed?

　　Julia: Good question.

　　Sergio: They say that soon they can put drugssintosfoods so that we can stay healthy by eating food.

　　Julia: It all sounds like science fiction to me. I hope they know what they are doing.

　　Sergio: Me too.
