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.

But why not D? If trees were cut down at point P, then why is the point at lowest pollution?

Ans 8:

Class : Class 5
The correct answer is option A

Ans 9:

Class : Class 5
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.

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:

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.
