Input: Consider Input: Context: Nowadays they are giving homework even during the holidays and I hate that very much. But I think there is a reason for it. Homework is given so that we can remember whatever we have learnt. Regular drilling and repetition make perfect. But teachers have started to give too much homework. Anything in excess is bad. Jane What's the use of just homework without allowing children to get an insight into the subject? It just makes them bookworms but nothing else. Homework such as writing some things 5 times at home will just make them memorize things but not put them into use. I regret to say that teachers find it easy to bundle the children with homework rather than making them get interested to understand what they learn. The same trend continues even in college. I find that most of the so-called high scorers are unable to answer simple things in an interview. Sally It is OK to give homework. But it should be given less. We are spending most of our time in school and at least we must be free in our home. If you give homework, we will be very tired and we wouldn't be able to pay attention to extra-curricular activities, which in turn may affect our physical and mental health. So please give less homework to us. Johnson It is part of our work to give students homework. There will be some punishments if we won't do our work. So I have to do that though I know such a teacher is not liked by students.

Input: Consider Input: Context: The fighting against youth smoking since I took office I've done everything in my power to protect our children from harm. We've worked to make their streets and their schools safer, and to give them something positive to do after school before their parents get home. We've worked to teach our children that drugs are dangerous, illegal and wrong. Today, I want to talk to you about the historic opportunity we now have to protect our nation's children form an even more deadly threat: smoking. Smoking kills more people every day than AIDS, alcohol, car accidents, murders, suicides, drugs and fires combined. Nearly 90 percent of those smokers lit their first cigarette before they turned 18. Consider this: 3,000 children start to smoke every day illegally, and 1,000 of them will die sooner because of it. This is a national tragedy that every American should be honor-bound to help prevent. For more than five years we've worked to stop our children from smoking before they start, launching a nationwide campaign to educate them about the dangers of smoking, to reduce their access to tobacco products, and to severely restrict tobacco companies from advertising to young people. If we do these, we'll cut teen smoking by almost half over the next five years. That means if we act now, we have it in our power to stop 3 million children from smoking and to save a million lives as a result.
Question: How many children will be stopped from smoking if we act now?
Output: 3 million
