I want to know the answer to the following question:
Several proposals have been raised to do what?
All the background I'm provided with is that "In observance of Shabbat, in places where Friday is a work day and the majority of population is Jewish, Friday is a "short day", usually lasting till 14:00 in the winter, or 16:00 in the summer.". Is that enough to answer the question?
Answer: no
