The student provides a focused and detailed description of the main topic, which is to explore the relationship between the structure (length of the carbon chain) and enthalpy of combustion and boiling point of alcohol. Additionally, the student presents a well-organized and concise background information section that explains each of the concepts needed to understand the topic of investigation. The methodology of collecting data for the chosen alcohols from two different databases is highly appropriate, and the student correctly identifies the independent and dependent variables to pursue the research question. Finally, the student lists the variables that have to be controlled or maintained constant for the results to be valid.
