B and C both are correct. Wolf is a carnivore. But in solution they have given 'Jackal'. SOF requesting you to either 1. Change the word 'Jackal' to 'Wolf' in solution and then change option D to 'Both B and C' OR 2. Change 'Wolf' in Option C to 'Jackal'. Pls. change according to any one of the points above ASAP to avoid confusion.

The answer cannot be B because the timeline Q-R is a decrease in pollution whereas if a factory was set up in point Q.Q-R would be an increase of pollution and not a decrease.In point P trees were cut and because of that P-Q is an increase in pollution and not a decrease .So,the answer is not B but A.

Harshit from Army Public School, Lucknow

Hi friend. The ans is (A) 100 because on richter scale the magnitude is increased ten times every number. for example 2 is 10 times 1 on richter scale.

Ans 5:

Ayush Gorain from Sarala Birla Public School, Ranchi
Class : Class 8
In my opinion, the answer should be option (A) instead of option (B). On the Richter scale (which is a non-linear scale), the power of an earthquake increases by 10 with every consequent number. Thus, an earthquake of 2 on the Richter scale is 10 times more powerful than an earthquake of 1 on the Richter scale. Thus, an earthquake of 8 on the Richter scale is more powerful than an earthquake of 6 on the Richter scale, by a factor of 10⁸⁻⁶, or 10². Thus, an earthquake of 8 on the Richter scale is 100 times more powerful than an earthquake of 6 on the Richter scale.
