I'm stuck on two quiz questions that I'd really appreciate help with.
Which is the odd one out of these letters and why - B C F H I K N P S U V Y?
The second question asks for the name of the person who wrote a well-known poem entitled ' Poor Old Lady'. I've never heard of the poem and can't find any reference to it and it is not a poem of a similar title by W C Williams or the anonymous one about a lady swallowing a fly etc.
...but maybe, on a similar vein, they are all single letter chemical symbols but K (potassium) is the only one which isn't the same as the first letter of the element it represents.
