The inclusion of interviews with community members drawing a sketch map and any other illustrative material in South Africa helps in the effectiveness of qualitative scientific research.
<h3 /><h3>What is qualitative scientific research?</h3>
It is an approach whose scope focuses on understanding societal phenomena through the study of subjective aspects such as culture, behavior, place and time. The collection of data and information is usually done in a more comprehensive way, and interviews, case studies and analysis techniques can be carried out to understand the hypotheses.
Therefore, the use of a sketch map or illustrative material may be appropriate in conducting qualitative research in South Africa, in order to reduce communication and cultural barriers that may arise and imply the effectiveness of the research.

Answer: B. -4
The slope is definitely negative, so you can cross out A and C. The slope of a line is always y/x. If you look at the point (-1,-1,) look up to point (-2,6.)
Comparing the two points I mentioned above, the y difference is 4 while the x difference is 1. This is also -4/1, meaning that the answer is B.
Answer:
Explanation:
The refractive index of the suspected glass can be known by using the backe- line method. This process takes place in a petrographic microscope. In this method an oil comparable to the refractive index of the glass is used. At a point when the refractive index of the glass becomes equal to that of the oil in which it is immersed the yellow line under the observation of the plane polarized light gets disappeared. This method can be used to identify the refractive index of the suspect glass and comparing it with the source of origin or sample glass.
