Answer:
The correct answer will be-
Case I- option-B
Case-II-option-B
Explanation:
A scientific method is the best procedural approach to explain the natural phenomenon. The method includes various steps which begin with the making the observation. The observation leads to the asking the scientific questions which could be answered by proposing a hypothesis.
The hypothesis must be tested through experiments which could prove and disprove the hypothesis and can answer the natural phenomenon.
<u>Case-I</u>
In the given situation of the question in which a person notices or observes the fields of grass and grass and native flower. Since the researcher notices the fields, they are performing the first step of the method that is "making an observation" and thus Option-B is the correct answer.
<u>Case-II</u>
In the situation, which discusses the number of birds in the fields shows the "dependent variables". The dependent variable is the parameter which is studied in the experiments. Since in the given conditions the number of birds is being studied, therefore, Option-B is the correct answer.
The Congo and Niger rivers have interesting irregular courses, and instead of going just in a certain direction, they circle around big areas. This is due to the shape of the landscape, and also because of the types of rocks in the surrounding areas where these two rivers flow.
The shape of the landscape is crucial in the course of a river, since every river is moving through the lowest parts where there isn't obstacles, so these rivers have followed that pattern and it turned out to give them irregular course. Also, the types of rocks on their way are very important, so these rivers managed to get through the sediment rocks as they are easy to erode, but haven't been able to break through the igneous rocks that are much harder.

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.
