In the last decade or so, there has been a dramatic expansion of small retail convenience stores (such as 7-Eleven, Kwik Shop, and Circle K), although their prices are generally much higher than prices in large supermarkets. The success of these convenience stores can be partially explained by
1. cost savings due to their smaller size.
2. the time consumers save when purchasing goods there.
3. diseconomies of scale.
4. the high prices they charge.

2) the time consumers save when purchasing goods there.

Explanation:

Their name explains everything. A convenience store is a store where someone can go and purchase goods easily and without any type of difficulty.

Of course a Walmart is cheaper, but will you travel 20 minutes just to get there, and spend 20 more minutes choosing and paying for a cheap good like a Coke, and then 20 more minutes back home. Whatever you save on buying the Coke, you will spend 50 times more in gas and personal time.

So even if a Coke costs $1 more in a 7-Eleven, it is worth it. You will save a lot of money by purchasing your Coke there.

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.
