In the cambridge encyclopedia of language (cambridge university press,1987), author david crystal presents five sentences that make a reasonable paragraph regardless of their order. the sentences are as follows: mark had told him about the foxes. john looked out the window. could it be a fox? however, nobody had seen one for months. he thought he saw a shape in the bushes. how many different five-sentence paragraphs can be formed if the paragraph begins with "he thought he saw a shape in the bushes" and ends with "john looked out of the window? "

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

answer: 48
