Select the most appropriate option for blank No. 4.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. unknown.
- The sentence refers that around 500 B.C. Pythagoreans argued for a healthy, vegetarian food but the term 'vegetarianism' was not known during his time and so it was known as the 'Pythagorean diet'.
- So, the most appropriate word that will fill the blank no. (4) is 'unknown', which means 'not known or familiar'.
