Let us look at the timeline of the major events in the Indian National Movement:
- Champaran Satyagraha (1917): Gandhi's first civil disobedience movement.
- Jallianwala Bagh Massacre (1919): A brutal incident in Amritsar led by General Dyer.
- Peasant Movement in Bardoli (1928): Led by Sardar Vallabhbhai Patel in Gujarat.
- Second Round Table Conference (1931): Attended by Mahatma Gandhi in London.
Thus, the correct chronological order is: Champaran Satyagraha → Jallianwala Bagh Massacre → Bardoli Movement → Second Round Table Conference.

A racing track is built around an elliptical ground whose equation is given by \[ 9x^2 + 16y^2 = 144 \] The width of the track is \(3\) m as shown. Based on the given information answer the following: 
(i) Express \(y\) as a function of \(x\) from the given equation of ellipse.
(ii) Integrate the function obtained in (i) with respect to \(x\).
(iii)(a) Find the area of the region enclosed within the elliptical ground excluding the track using integration.
OR
(iii)(b) Write the coordinates of the points \(P\) and \(Q\) where the outer edge of the track cuts \(x\)-axis and \(y\)-axis in first quadrant and find the area of triangle formed by points \(P,O,Q\).
