To fill in the sentences, use comparative adjectives to emphasize the differences, such as 'more careful' for careful and 'more politely' for polite. Other examples include 'harder-working' for hard and 'more slowly' for slow. These forms highlight the comparisons being made between the subjects mentioned.

The question you have asked involves completing sentences with adjectives, which is a part of learning comparative and superlative forms in English grammar. Let's look at each sentence and the necessary changes:
Early :
In the context given, the adjective "early" is used to describe when someone gets up in the morning. After completing the sentence, it is: 'Mum gets up earlier than Dad in the morning. She gets up early.'
Careful :
Here, the focus is on how carefully the homework is done. So, the complete sentence will be: 'I do my homework more carefully than my brother. I am more careful than him.'
Hard :
In this case, "hard" is used to describe the intensity of studying. The completed sentence will be: 'Tia studies harder for her exams than me.'
Slowly :
"Slowly" describes the speed at which Grandma drives. The full sentence is: 'Grandma drives slowly at night. She drives more slowly than Granddad.'
Polite :
Here, "politer" compares how Pete communicates compared to Jamie. The full sentence would be: 'Pete is politer than Jamie. He talks to the teacher more politely than Jamie.'
These sentences illustrate how comparative forms of adjectives are used to show differences between two entities. Typically, shorter adjectives add "-er" (like "earlier" or "harder"), while longer adjectives use "more" (like "more carefully" or "more politely"). This understanding will help improve your skills in writing and comparing various subjects in English.
