Final answer:
Mortimer convinces Abby and Martha to commit to a mental institution in "Arsenic and Old Lace," while characters in other texts are persuaded or decide to change their living spaces.
Step-by-step explanation:
Mortimer persuaded Abby and Martha to make changes to their home in the dark comedy play "Arsenic and Old Lace" by Joseph Kesselring. In the narrative described, however, there is no explicit reference to Mortimer persuading Abby and Martha to do anything to their home specifically.
The referenced texts deal with different characters and scenarios persuading or taking significant action to change their living spaces for various reasons, from comfort after realizing the potential of a new barn to creating an expensive nursery for children. Therefore, if you're asking in context to "Arsenic and Old Lace," Mortimer convinces his aunts to commit to a mental institution.
In a general sense, characters in the cited texts are persuaded, or decide themselves, to take significant actions altering their home environments to better suit their needs or reflect their desires.
