By adding new product lines beyond its core business of computer software, like the surface pro tablet and xbox 360 game system, microsoft primarily benefits bya. keeping up in a market where sales come mostly from new products. b. satisfying the changing needs of the technological research staff. c. avoiding market saturation from products that have just been introduced to the market. d. creating diversification and reducing risk. e. spreading out production costs.

The answer is letter D.

Explanation:

Microsoft primarily benefits by creating diversification and reducing risk.

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.
