Answer: Placebo effect
John is experiencing placebo
effect where the pill that contains no pain killing medication has given pain
relief to John. A placebo is a substance with no therapeutic effect but sometimes
improves patient’s condition. This is due to patient’s expectation that the
pill they take can help or ease the pain they have even if no active ingredient
is present.
Therefore, the effect is more
than positive thinking or believing that a treatment will work by creating a
stronger connection between the brain and body as they work together.

Answer: Heat produced from the electric ice cream maker killed the grass
Explanation:
The principle behind refrigeration of the ice cream maker is that
- air from the atmosphere is collected into the condenser,
- it is mixed with refrigerant gases like liquid nitrogen
- then it becomes cool, and freezes the prepared cream to become iced
- then, the HEAT generated during this conversion is ejected from the electric ice cream maker in form of hot air.
This hot air directed towards the grass will kill its living cells, thus it turns yellow over time
