03　Answers and one-line notes

#	Answer	One-line note
1	Grains such as rice, bread and noodles.	The bottom group should be eaten most and mainly supplies carbohydrates.
2	Water aids digestion, carries nutrients and controls body temperature.	Without enough water, digestion and cooling suffer, so drink regularly.
3	It reduces the germs that enter the gut with food.	Clean hands cut the chance of food poisoning from germs on the fingers.
4	The stomach.	The stomach is a bag that holds food and churns it with juice into a paste.
5	Vegetables, fruit and wholegrains.	Plant foods carry more fibre than refined foods.
6	It keeps the digestive system in rhythm and avoids getting too hungry or too full.	Regular meals keep digestive juices on schedule and reduce stomach pain.
7	850 kcal	Two thousand minus 450 minus 700 gives 850 kcal.
8	8.0 per cent	Sixteen divided by 200 times 100 gives 8.0 per cent.
9	27.0 per cent	Sixty times nine gives 540 kcal, and 540 over 2000 times 100 gives 27.0 per cent.
10	No.	Most nutrient absorption happens in the small intestine; the large intestine mainly takes back water.

04　What to do after marking

After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
Repeat the same item two days later; move to the next paper only when both attempts are correct.
Parents only need the answer and note columns; there is no need to explain every item.

With all four done, go back to the chapter page and revise the three parts of a closed circuit plus three safety habits.Tutor Registration →
