Answer the following question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "In Britain, Willett's 1907 proposal used the term daylight saving, but by 1911 the term summer time replaced daylight saving time in draft legislation. Continental Europe uses similar phrases, such as Sommerzeit in Germany, zomertijd in Dutch-speaking regions, kesäaika in Finland, horario de verano or hora de verano in Spain and heure d'été in France, whereas in Italy the term is ora legale, that is, legal time (legally enforced time) as opposed to "ora solare", solar time, in winter."?
