Standing Waves on a String: True/False Questions

[BMWPower06]

Homework Statement

A string of length L is stretched horizontally between two fixed points. When the string is plucked vertically, standing waves can be formed on the string. Which of the following statements are true about this situation?
True False The waves on the string are transverse waves
True False The highest resonant frequency is called the fundamental
True False Each end of the string must be a node
True False The middle of the string can never be a node or an antinode
True False It is possible for half a wavelength to fill the length of the string

The Attempt at a Solution

Answers are in bold, from reading through the chapter in my book i was able to come up with those answers, now the website says I am wrong but it doesn't tell me which one is wrong. Can any1 maybe help lead me in the right direction?

Thanks

The second one is false.

The fundamental note has the longest wavelength and therefore the lowest frequency.
