Help with a Christmas quiz

The Walrus and the CarpenterWere walking close at hand;They wept like anything to seeSuch quantities of sand:"If this were only cleared away,"They said, "it would be grand!" "If seven maids with seven mopsSwept it for half a year.Do you suppose," the Walrus said,"That they could get it clear?""I doubt it," said the Carpenter,And shed a bitter tear.

Nice alan h. Well done. Thank you.

Beggared if I can sort this one - I agree it shouldn't be body temperature [as the value is not constant] Will think on ..................

Normal human body temperature, also known as normothermia or euthermia, is a concept that depends upon the place in the body at which the measurement is made, and the time of day and level of activity of the body. Although the value 37.0 °C (98.6 °F) is the commonly accepted average core body temperature, the value of 36.8±0.7 °C, or 98.2±1.3 °F is an average oral (under the tongue) measurement.[1][2] Rectal measurements, or measurements taken directly inside the body cavity, are typically slightly higher. In Russia and former Soviet countries, the commonly quoted value is 36.6 °C (97.9 °F), based on an armpit reading. The core body temperature of an individual tends to have the lowest value in the second half of the sleep cycle; the lowest point, called the nadir, is one of the primary markers for circadian rhythms.
