Thanks again for this, imagcq.
Here is my stab at it.
1) Behind time contrive to be not that well (5/1/7) After a fashion?
Behind time – after, with contrive - fashion. After a fashion is “not that well”
2) Apology to nation in dreadful mess (5/5) Sorry state?
Apology – sorry, with nation –state. Sorry state is “dreadful mess”
3) Food served up for us but temperature's dropped low (13) Dishonourable?
“Food served up for us” is “Dish on our table”, with t for temperature dropped gives “dishonourable” = low.
4) I note circular shape in cold weather condition (7) Rainbow?
Raw- cold with I and NB (note) and o (circular shape) gives Ra I nb ow- a weather condition.
This gives ANSEDERW, which gives Answered?
