   CRITICAL THINKING                                           EXAMPLES
                                 People are becoming worried about the dangers of using mobiles too

 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

                                 Consumers Association reported that hands-free kits increase the
                                 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

 5. Describe the reasons         The hands-free set was chosen as a solution because exposure to

 6. Evaluate this solution       Some research shows hands-free mobile phones reduce the amount of
                                 radiation that reaches the ear, but other research by the *Consumers

 7. Suggest a solution to
        the problem              In my opinion, firstly, you should buy a phone with a long talk ‘time’ and

     best way to solve this
8. 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
                                  when the signal is not strong the phone needs more power and gives off

    What evidence is there
  that your solution will work?
9. Describe possible
                                  If people follow my advice, fewer mobile phones with short ‘talk times’
