One of the disadvantages of methods of system development is that the overall project might be subject to scope change as user requirements change.

The correct answer is agile.

Explanation:

Agile software development methodologies are essential in a world in which things change at vertigo speed. The programmers live worried about what are the latest trends, which languages or practices are obsolete and with the constant sword of Damocles to think that what we are developing today may not help tomorrow.

The world of development, for better or for worse, has evolved from a model in which all phases were planned and carefully structured to a model in which development should be as fast and efficient as possible. Personally I am a big fan of agile software development methodologies, how many principles are stated in this manifesto.

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.

what are the sentences? so we can answer the question.
