Final answer:
The wealthy English landlords had differing responses to their starving tenants, some helped while others ignored the crisis or threw their tenants off the land. Liam McManus's situation is a specific example of this.
Step-by-step explanation:
The central idea of the paragraph is that the wealthy English landlords had differing responses to their starving tenants. Some landlords helped their tenants by instructing their agents to divide up leftover food, while others ignored the crisis or threw their tenants off the land if they couldn't pay the rent.
A detail that does not support the central idea is that Liam McManus's parents died and they had to leave their property. This detail is specific to one landlord, rather than a general response among wealthy English landlords.
The topic of the paragraph is the relationship between the wealthy English landlords and their starving tenants.
