Thank you Patrich. I am sure you are correct but I don't know why they used a capital letter in the middle of a sentence to confuse me! Are you able to parse 5 down? Many thanks.
A bit perplexed by 5d, trelos1. Not sure why ‘say’ is there, unless it is ‘e.g.’, which would leave a = age, which I have never seen and isn’t in Chambers. And I agree, agile doesn’t really mean still going strong.
