2.12 describe the qualitative variation of resistance of LDRs with illumination and of thermistors with temperature

An LDR is a light dependant resistor. Its resistance changes with the intensity of light. It has a high resistance in the dark but low in the light. A thermistor is a temperature dependant resistor. In hot conditions there will be less resistance but in cold conditions there will be high resistance.
