Hi, which of the following sentences do you prefer and why?
1. Due to her extreme dislike of cold temperatures, she refuses to let her tenants set the thermostat below 25 C.
2. (...) she refuses to let her tenants set the thermostat anywhere below 25 C.
2. (...) she refuses to let her tenants set the thermostat any lower than 25 C.
4. (...) she refuses to let her tenants set the thermostat to less than 25 C.
Also, in each case, would it be preferable to say "she won't let her tenants..." rather than "she refuses to let her tenants..."? Is there any subtle difference between the two I should be aware of?
More formally and generally speaking, would it also be acceptable to say: "She refuses to let her tenants adjust the thermostat to suit / meet their individual needs"?
