Engineer: Cranes are expensive to hire and must be operated by trained and certified operators, who charge high hourly rates. We could reduce our expenses by hiring more workers instead of using a crane for our current building project.
Site manager: That would not work. Hiring a crane will help us complete the project in the most efficient way.
Which of the following, if true, most strengthens the site manager's objection to the engineer's proposal?
A. A large percentage of the accidents that occur on construction sites are related to the misuse of cranes.
B. While some are mobile and some are not, there are many types of crane, each suited to a specific set of functions.
C. In the recent year, construction workers' wages increased by 23%, while that of crane operators increased by only 5%.
D. Because they are not restricted to using routes on the ground for the relocation of objects, cranes can perform tasks that no number of workers can.
E. The use of a crane in a building project is always accompanied by high insurance premiums.
Site manager: That would not work. Hiring a crane will help us complete the project in the most efficient way.

OFFICIAL EXPLANATION
Engineer: Cranes are expensive to hire and must be operated by trained and certified operators, who charge high hourly rates. We could reduce our expenses by hiring more workers instead of using a crane for our current building project.
Site manager: That would not work. Hiring a crane will help us complete the project in the most efficient way.
Which of the following, if true, most strengthens the site manager's objection to the engineer's proposal?
A. A large percentage of the accidents that occur on construction sites are related to the misuse of cranes.
Incorrect.
This is a Conclusion Strengthening question in the Dialog format. You are asked to choose the answer choice which strengthens the site manager's objection (or weakens the engineer's proposal):
This answer choice weakens the site manager's objection by presenting a negative aspect of using cranes - they cause more accidents.
B. While some are mobile and some are not, there are many types of crane, each suited to a specific set of functions.
Incorrect.
This answer choice neither strengthens not weakens the site manager's objection as it too general and does not necessarily promote the use of cranes.
The fact that there are many types of cranes does not necessarily mean that there is one that perfectly suits the need of the project in question, or that it will help complete the project in the most efficient way.
C. In the recent year, construction workers' wages increased by 23%, while that of crane operators increased by only 5%.
Incorrect.
While it may seem to support hiring more crane operators, this answer choice neither strengthens not weakens the site manager's objection. The percentage of rise in wages does little to support either side as we do not know their original wages. For example, though the construction workers' wages rose by more percents, the crane operators wage could be 300% greater to begin with.
Be careful not to confuse a greater trend, that is a rise or drop, with a greater absolute number (the result of that rise or drop).
D. Because they are not restricted to using routes on the ground for the relocation of objects, cranes can perform tasks that no number of workers can.
This answer choice indirectly strengthens the site manager's objection by weakening the proposal made by the engineer. The claim that more workers could compensate for the lack of a crane is weakened by this answer choice which states that there are some things that human workers simply cannot do, no matter how many workers are involved.
E. The use of a crane in a building project is always accompanied by high insurance premiums.
Incorrect.
This is a Conclusion Strengthening question in the Dialog format. You are asked to choose the answer choice which strengthens the site manager's objection (or weakens the engineer's proposal):
This answer choice weakens the site manager's objection. Stating that the use of a crane involves paying high insurance premiums only leads us to believe that hiring a crane will result in increased expenses. However, our task is to find a statement that supports the site manager's viewpoint that the use of a crane will increase the efficiency of the project.

Conclusion (Site manager)- Despite they are expensive, cranes are more efficient in the completion of the project than hiring more workers.
We need to strengthen this conclusion by giving strength to the reasoning how cranes are better.
Let's see the choices now.
A. A large percentage of the accidents that occur on construction sites are related to the misuse of cranes.
This choice supports the engineer's point to opt out the usage of cranes.
B. While some are mobile and some are not, there are many types of crane, each suited to a specific set of functions.
This maybe true, but does not explain how the cranes can better help in the completion of the project. No impact on the argument
C. In the recent year, construction workers' wages increased by 23%, while that of crane operators increased by only 5%.
Until we don't know the initial wages , we can't say which one is expensive - wages of workers or wages of operators. No impact on argument.
D. Because they are not restricted to using routes on the ground for the relocation of objects, cranes can perform tasks that no number of workers can.
Correct. This gives a reason why cranes are better than workers. Supports the site manager's point.
E. The use of a crane in a building project is always accompanied by high insurance premiums.
This choice, if at all, supports the engineer's point that cranes are expensive.
IMO D
