Consider the following : 1. Calcutta Unitarian Committee 2. Tabernacle of New Dispensation 3. Indian Reform Association Keshab Chandra Sen is associated with the establishment of which of the above?

States Keshab Chandra Sen helped Atmaram Pandurang found the Prarthana Samaj in Bombay (1867), showing he took part in founding new reform organisations outside his immediate base.

A student could infer that since Sen co-founded societies elsewhere, it is plausible he might also have been involved in founding other bodies in Calcutta and should therefore check records of the Calcutta Unitarian Committee for his name or correspondence.

Notes Sen's role in popularising the Brahmo Samaj and opening branches in multiple provinces, indicating a pattern of organizing and institutional expansion.

Combine this pattern with knowledge that Unitarians and liberal Christian groups sometimes collaborated with Brahmo leaders to search archival lists of founders/meetings for Sen's participation.

Gives the scale of organisational growth under Sen (54 Samajas by 1865), implying he actively promoted and established formal bodies and committees.

Use this as a reason to inspect organisational founding dates and minutes of Calcutta committees from the period to see if Sen's leadership role extended to a Unitarian committee.

Records that Keshab Chandra Sen visited and lectured in Madras, indicating he travelled and engaged with reform networks outside Bengal.

Given his mobility and networking, a student might look for evidence of his involvement in urban Calcutta committees (such as Unitarian groups) in travel accounts, lecture notices or society membership lists.
