Read paragraphs 2-6, and answer the question: What are the three creative steps that the writer takes to catch the snakes without hurting them?
My third attempt repeated the second procedure.
The next morning I carried in my hand a small net
used for catching fish. This was in the expectation
that the snakes would bite again. But monitored
carefully, the snakes proved to be no trouble and
all went according to plan. I collected the passive
snakes and the next day we merrily released them
all back into the wild.
I decided to use the last one. I bought an ice-cream
maker which was made of stainless steel. Between
the outside and the inside walls of the bowl there
is some jelly, which freezes when cooled. I put the
bowl into the fridge and waited for 24 hours. At the
same time I prepared some ice-cubes.
Step 1, She bought a stainless steel ice cream
maker and froze the bowl. she added ice cubes
to the top of the bowl to keep it cold. She placed
it over the snakes’ habitat during the day so that
the snakes would become sleepy and could be
easily caught.
Step 2 As above she did the same but placed the
bowl over the snakes’ habitat in the evening
Step 3 As above but added a net to catch the snakes.

Here was a chance for the writer to distinguish herself, Because she knew that her
parents would not like her to kill these living creatures.
2. I decided on 3 possible approaches: first, removing the habitat, second, attracting
them into a trap using male or female perfume and food.
3. For the first attempt, After 2 hours waiting, I removed the bucket and the bowl,
though the snakes were less active, they could move still too fast for me.
4.For the second attempt I froze the bowl and ice cubes again, but placed them over the
snakes' habitat in the morning.
5. If your new ideas are truly novel, you can get them accepted by the patent office.
