Consider the following statements :
- 1.Some mushrooms have medicinal properties.
- 2.Some mushrooms have psycho-active properties.
- 3.Some mushrooms have insecticidal properties.
- 4.Some mushrooms have bioluminescent properties.
How many of the above statements are correct?
Show answer
Answer: D. All four are true. Some mushrooms are medicinal (reishi, cordyceps). Some are psychoactive (Psilocybe). Some kill insects: the fly agaric (Amanita muscaria) has long been used to kill flies. Some glow in the dark (bioluminescent species found in the Western Ghats and North-East India).
Watch for: The word 'some' makes each statement easy to satisfy; do not treat unusual ones like glowing mushrooms as fake.
Why the other options are wrong
- A. Wrong because all four properties are found in some mushrooms.
- B. Wrong because all four properties are found in some mushrooms.
- C. Wrong because bioluminescent and insecticidal mushrooms also exist.
