Conclusion
They were asked the question, "Do you think mobile phones cause health problems?" Figure 2 Many people suffer from minor health problems after using a mobile phone.

Summary
This piece of work contains some useful information on the advantages and disadvantages of mobile phones. The writer has picked out some good ideas of how they think the technology of mobiles has positive and negative impacts on people.
Some suggestions for improvement...
1. More examples need to be provided for the advantages and disadvantages. Most of the advantages seen by some users can be viewed as disadvantages by others. So for example, "Being contactable all the time provided there is a signal" could then be explained in terms of being a disadvantage and then as an advantage.
2. More information about the data collected by surveys - who were the audience, when was the data collected, how was the data collected and what is the best way to present the findings.
3. Balance - there is quite an emphasis on the health implications and this overrides the other points that have been made. If the other points were addressed in as much detail then this would be a very well rounded piece of work.
The quality of written communication is generally good although "phone" should really be "telephone" of be preceded by an apostrophe " 'phone".
As it stands this is a 3 star piece of work. It is too short to contain a real evaluation of the advantages and disadvantages of mobiles but it shows promise.
