Every sheet in June 1972
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st June 1972Give one way of reducing the spread of malaria.
- 2nd June 1972A patient's core body temperature has fallen to 35 degrees Celsius. State two physical responses their body makes to raise it back toward normal.
