Answer 2

Hey friend,

The British government issued the Simon Commission

Simon commission is one of the factors leading to the civil disobedience movement!

This commission was appointed in November, 1927
The Simon commission is named after Sir John Simon, who was the chairman of the commission.
The commission was appointed by the British Government to investigate the need for further constitutional reforms.
The commission had seven British members but no Indian members.
This was seen as a deliberate move to insult the self-respect of Indians

In 1927, the Congress decides to boycott the commission 'at every stage and in every form'.
Even the Muslim League agreed to boycott the commission. 

Next year, an 'All India Hartal' was organized by the people. When the commission reached Mumbai, people greeted the commission with slogan "Simon Go Back".
during these protests and hartals...Lala Lajpat Rai was arrested and beaten up.

Finally, the commission was sent back with some suggestions and recommendations. 

Hope it helps!
