Section A, Question 1:

Spider:
- Starts at 0 cm
- Ends at 6 cm
→ So, the spider is 6 cm long.

Ladybird:
- Starts at 0 cm
- Ends at 3 cm
→ So, the ladybird is 3 cm long.

Stick insect:
- Starts at 0 cm
- Ends at 8 cm
→ So, the stick insect is 8 cm long.

Now, order them from shortest to longest:
- Ladybird: 3 cm
- Spider: 6 cm
- Stick insect: 8 cm

So the order is:
ladybird, spider, stick insect

Question 2:

Caterpillar:
- Starts at 0 cm

Now, order them from shortest to longest:
- Bug: 4 cm
- Ant: 8 cm
- Caterpillar: 9 cm

So the order is:
bug, ant, caterpillar
