Incorrect Statements:
a) Tarapur Massacre of Bihar occurred in the year 1932.
b) Hanging of Bhagat Singh, Sukhdev, and Rajguru was the only reason for the protests in Tarapur.

Explanation:

Tarapur Massacre of Bihar:
The Tarapur Massacre, also known as the Chauri Chaura incident, did not occur in Bihar, as stated in statement 1. It actually took place in Uttar Pradesh in the year 1922. The incident took place in the village of Chauri Chaura, where a peaceful protest turned violent, resulting in the death of 22 policemen. This incident had significant repercussions on the Indian independence movement and influenced Mahatma Gandhi's decision to call off the non-cooperation movement.

Hanging of Bhagat Singh, Sukhdev, and Rajguru:
Statement 2 claims that the hanging of Bhagat Singh, Sukhdev, and Rajguru was the only reason for the protests in Tarapur. However, this statement is incorrect. The Tarapur Massacre had occurred several years before the hanging of these freedom fighters.

The hanging of Bhagat Singh, Sukhdev, and Rajguru took place on March 23, 1931. They were executed for their involvement in the Lahore conspiracy case and the assassination of British police officer John Saunders. While their execution did spark widespread protests and outrage among the Indian population, it cannot be considered as the sole reason for the protests in Tarapur.

Reasons for the Protests in Tarapur:
The actual reasons for the protests in Tarapur were related to local grievances and issues faced by the villagers. The protests in Tarapur, also known as the Tarapur peasant struggle, took place in Tarapur village of Ballia district in Uttar Pradesh. The movement was led by Swami Sahajanand Saraswati, a social reformer and peasant leader.

The main demands of the peasants were:

1. Reduction of revenue and rent: The peasants demanded a reduction in the land revenue and rent, which were excessively high and burdened the farmers.

2. Abolition of the Zamindari system: The protesters called for the abolition of the oppressive Zamindari system, which exploited the peasants and kept them in a cycle of poverty.

3. Land reforms: The peasants demanded land reforms to ensure equitable distribution of land and to provide land to landless farmers.

4. Change in agricultural policies: The protesters sought changes in agricultural policies to support farmers and improve their conditions.

The protests in Tarapur were part of the larger peasant movements that were taking place across India during that time. These movements aimed to address the agrarian issues faced by the rural population and played a significant role in shaping the social and political landscape of the country.

In conclusion, both statements 1 and 2 are incorrect. The Tarapur Massacre did not occur in Bihar in 1932, but rather in Uttar Pradesh in 1922. Additionally, the hanging of Bhagat Singh, Sukhdev, and Rajguru was not the sole reason for the protests in Tarapur. The protests were primarily driven by local grievances and demands for agrarian reforms.
