2. She couldn't reach the lower hanging foods, so she's got to find a ladder near her house.

3. They had some arguments last and one of their neighbors called the police.

If you start studying harder today, you'll have a better chance of passing the exam/passing exams. (Studying harder implies more than the usual amount, so no need to add 'than usual')
