Hello, i'm french and i need help for write a text in english (200 words) :
You have decided to enter a competition in which you have to present a new invention that you think would be useful to many people. Write a report dealing with the aspects suggested below. (200 words)
a. How the idea came to you.
b. What items already exist on the market and why they are not satisfactory.
c. Your invention: description, materials used, size, function, how it works etc...
d. How it would improve things for people (advantages).
e. In terms of cost, how expensive it could be to produce.

BE CAREFUL, you have to make me gain a maximum of points, for its you have to respect the rules (It's written in French but I translated it with Google translation) :

0 to 3 points :
- this is a hypothesis
- the utility of the imagined invention is demonstrated
- the text is written and presented taking into account the formal context (competition)
- the expected elements (a, b, c, d, e) have been provided
- the text produced contains between 175 and 250 words.

I want a maximum of points, so you must respect the important points of the written expression (5 - 7 points) :
Can write detailed, non-complex descriptions.
Can write a text using simple language to list the advantages (and disadvantages), give and justify his opinion.
