Mike always has to adjust the blinds in his office because of the sunlight. what could be a solution to develop a better set of window blinds? a) install a timing mechanism and set it to open or close at a specific time b) install a sensor that monitors the amount of sunlight c) buy better window blinds d) buy darker window blinds

B

Explanation:

A sensor, usually photoelectric, that monitors the intensity of sunlight is better because, in case of high intensity, the blinds are automatically closed or almost closed allowing little sunlight to enter through and light up the office. In case of low-intensity sunlight, the blinds automatically open or are more open allowing much of the sunlight from outside. This way Mike does have to keep adjusting his blinds.

explanation:

substitution is the answer in this case
