Scroll down below "How to Google" and read, read, read. However, keep in mind this was first published online in November 2011. So, as Ms. Sue said, your information [and I'll add, this webpage's information, too] is out of date. Google's programmers have made the search engine "smarter" as time has gone on.
The best query to use when searching for the answer to the question "What causes tornadoes?" is B) Tornadoes OR causes.
This query uses the Boolean operator "OR" to include results that mention either tornadoes or causes. By using this query, you will get a wider range of information and increase the chances of finding relevant sources that discuss the causes of tornadoes.
