Read the following article and select the best answer. Article: A private sixth grade is set to start its lessons at 1.30 pm every day because the school's teacher thinks his students will study better after a morning lie-in . Instead of rising early for a 9 am start, students at the PS15,000-a-year Hampton Court House, in East Molesey, Surrey, will get to enjoy a lie-in and work from 1.30 pm until 7pm. Head teacher Guy Holloway says the move for all sixth grade students, set to begin from September, has been made according to research by scientists. He predicts that not only will his students aged 16 and upwards get great night's sleep, but their productivity will also be improved. The co-educational school will have the latest start time in the UK, and will be the only one to begin lessons in the afternoon. Experts say young people are programmed to get up later, and that rather than laziness it is simply a shift in their body clocks. 'There are 168 hours in a week and how productive they are depends on how they choose to use those hours,' said Mr Holloway. 'At Hampton Court House we don't think we have the answer for everybody; it's about what works in our school. We want to get them into a condition where they can get great sleep and study well.' He said students would also benefit from reduced journey times as they travel to and from school after rush hour . Year 10 student Gabriel Purcell-Davis will be one of the first of 30 A-level students to start at the later time. 'I want to wake up in my bed, not in my maths lesson,' said the 15-year-old. Lessons for all other students at the school will still begin at 9 am as usual. Question: Why did the school decide to start the class at 1.30 pm? - It may be good for students' study. - Students wanted a morning lie-in. - Students were often late for school. - Teachers wanted to have a good sleep in the morning.
A:
It may be good for students' study.
