**Core Concept:** This question examines understanding of how different research methods can be used in a single study and their logical order of operation. It tests the reader's understanding of qualitative vs. quantitative data and the sequencing of a study. **Step-by-step analysis:** 1. **Identify key terms:** 'initial quantitative analysis' refers to numerical analysis. 'a series of interviews were conducted to provide further context' refers to a follow-up of collecting interviews, which is qualitative data. 'meticulously recorded and analyzed' refers to the processing of information. 2. **Analyze the sequence:** the word 'following' implies the quantitative analysis took place first, which informed the interviews. The statement 'provide further context' suggest qualitative data was used to enhance understanding of numerical findings. 3. **Evaluate the options:** * **A:** The methods are not independent but interconnected because one informs the other. Thus, A is incorrect. * **B:** Interviews were used to provide further context after quantitative analysis, not to formulate hypothesis prior to. Thus, B is incorrect. * **C:** The statement directly says 'to provide further context' which suggests that qualitative data was collected to add to the quantitative data. Thus, C is correct. * **D:** There is no mention of the initial data being flawed. The author mentions the data was supplemented. Thus, D is incorrect. **Key Points:** * Qualitative data (e.g., interviews) can provide context and depth to quantitative findings (numerical results), and this is a common practice in research. * The words 'following' and 'further context' are crucial in determining the relationship between the two methods. * The temporal order is implied by the statement. **Error Prevention:** Option A is tempting for those who are unaware that both methods can be used in the same study. Option D can be appealing to someone who tends to assume that there must have been a mistake to warrant changing a method.
