Edison has always received the major credit for inventing the lightbulb, because of his development of the power lines and other equipment needed to establish the incandescent lamp in a practical lighting system. Others say that without the contributions of Latimer -whom developed a filament that lasted longer than those developed by Edison and the widespread use of electric lighting possible- he would have never created a working lightbulb. To what extent do you agree or disagree?

Tips:

• Introduction: Be sure to state the question in your own words (paraphrase the question)
• Support your opinion: Once you have made your opinion clear, you have to provide facts to justify your choice
• State the opposing point of view. You do not have to persuade the examiner about the opposing opinion, but it is important to state what it is. 
• Summarise your opinion.
