Pierceing/sucking or rasping?

I take the GA O&T Commercial applicators license Tuesday and I have a bug ID problem. The crappy blue book study material on page 6 lists thrips as a pierceing/sucking insect but on page 22 it says they rasp plant surfaces for food. I know this is the gov. talking but it seems one of these answers are wrong. Any Ideas?
