You are the product manager for Buckstars Coffee, a nationally distributed brand. Buckstars has been declining in absolute level of sales for the last four consecutive months. You ask the marketing research department to do a study to determine why sales have declined. The most appropriate research strategy is

Exploratory Research Strategy

Explanation:

Exploratory research is the form of research which is carried out in those scenarios wherein the problem is not clearly defined.

Such a research is concerned with obtaining clarity on the problem and not exactly aimed at finding out the solution to the problem. It helps in obtaining better understanding of the problem.

Such a research does not provide conclusive solution of the problem as such a research is driven by the motive of exploration i.e findings or inquiring about the problem and studying it's nature.

In the given case, Buckstar aims to determine the reason behind sales decline. Herein, the problem is not clearly specified. This means no parameters have been defined based upon which sales is dependent. This requires Exploratory Research Strategy.  

the correct answer would be b, when, queen, calder hall and london.

explanation:

we always capitalize words when a paragraph or sentence is starting, when an important name is used, when a place is being written, or simply when a noun is used, etc. so in this sentence, sentence is starting from 'when', so it will be written in capital letters. secondly, queen is considered to be an important person, so it will also be written in capital letter. next, the name of the town is mentioned, i-e calder hall, which will also be written in capital letters. in the last,   city name is being used, 'london', which will also be written in capital letters. so option b is the most appropriate one.
