Nadia stands at the whiteboard on Friday with the week's weather table, which is full.

The week's table: the thermometer, wind vane, rain gauge, barometer, hygrometer and anemometer readings. The Temperature column is shaded.

Miss Moreau asks her to show the week's morning temperatures in one picture.

Nadia marks a dot for each morning's temperature and joins the dots with a line. Wednesday's dot sits between two numbered lines.

So how warm was it on Wednesday morning?
