Hello Supriya,
The rise in free, do-it-yourself instructions on the Internet for home repairs has led to a decrease in revenue for home service technicians and an increase in the number of injuries caused by people who have attempted home repairs themselves. Unfortunately, not all of the do-it-yourself instructions on the Internet are written as well as they should be.
What the passage tells us is that there is a reduction in the revenue for home service technicians and an increase in the number of injuries caused by the people who have attempted home repairs themselves. The passage further mentions that this is because do-it yourself(diy) instructions are not as good as they should be. Our aim is to find which of the stated options could be inferred from the passage.
Now, let us analyze statements b and c.
b) Most people who are injured while attempting home repairs have done so while following instructions found in free do-it-yourself instructions on the Internet.
The passage does mention that the do-it-yourself instructions are not up to mark. However, nowhere does the passage suggest that the instructions are wrongfully written or have some flaws which led to the increase in accidents. We cannot even be sure of whether those who met with accidents followed the instructions states in the diy manuals religiously. They could have committed some mistakes which might have led to accidents. Since, we cannot be completely sure of whether option b is true or not, based on the information in the passage, this statement in clearly not the one we are looking for.
Now, let us analyze option c.
c) The overall sale of online do-it-yourself home repair instructions by home service technicians has not been equal to the loss of revenue the technicians have incurred due to free offerings of this sort of material.
We already know that the free sale of online diy home repair instructions has caused a decrease in revenue for home service technicians. Statement c tells us that home technicians also sell the diy home repair instructions online. However, even though they might sell these instructions online, the revenue generated by this sale would not be equal to the decrease in revenue due to free offerings. If these values were equal, then they would not have incurred any decrease in net revenue at all. They would have either faced a no profit-no loss situation or a profitable earnings as their loss in revenue earned by home repair would have been negated by profit generated by online sale of diy instruction manuals. However, the passage mentions that there is a reduction in revenue for home technicians and hence, this statement can be inferred.
Hope this helps! Let me know if you need any further clarification.
