Identify the problem[s] Some people think mobile phones are dangerous because radio waves Did you say clearly what they give off may cause cancer; another problem is that using mobile the problem[s] is or are? while driving can cause accidents etc……etc…… 3. Analyze the evidence A study done in …… has reported that using hands-free mobiles has lead to a 95% less radiation reaching the user. However, another study by the How strong is the evidence Consumers Association reported that hands-free kits increase the given? radiation reaching the user. 4. Compare and contrast One solution some people think is good is the hands-free set where the different solutions to user wears a headphone connected to the mobile, which is kept away the problem from your head.

Support your solutions with reasons and The reason for my first solution is that phones with long ‘talk times’ use less power and give off less radiation and for my second solution is that evidence when the signal is not strong the phone needs more power and gives off Why did you choose this more radiation. solution to the problem? What evidence is there that your solution will work? 9. Describe possible If people follow my advice, fewer mobile phones with short ‘talk times’ consequences of any will be sold and mobile phone batteries will last longer, as people will not solution you propose use them when the signal is weak. What will happen if people follow your solution?
