It does concern me a little when someone gets a new license and then asks questions like this.
If a person "studies to the test", as is often advocated by various sources, you don't learn what frequency ranges you can use, you only memorize the test pool related answers. And online example tests, and the propensity for people to use such as their only real study sources, don't help the case. i.e., because of question T1B06 you may know that Technicians have an authorization for voice in the 10 meter band, or because of question T1B04 you may know that 146.52 is in the 2 meter band, but no questions on the test ask you what are the band edges of the 10 or 2 meter band, and no question asks what are all the frequencies or bands a Tech may use.
The less you have interaction with other hams during the studying or learning process, the more likely you will just study to the test. Online, individual, test preparation, especially question based, vs background information based, tends to make this worse.
And even if a new licensee does know "the information can be found in Part 97", sometimes people absorb information better when it is presented in different ways.
