Bucket and spade would be right ,thanks(sorry , I missed the last dash- it is there on quiz)
Shirt and tie not as all vowels given and non in second word so crisp and dry looks right.
Water and soap not right as first word has only an'a' ( no 'e')so went for Darby and Joan.
Still mulling over 16 .....
Thanks to all
