A particular logistics routing protocol used in large distribution networks often leads to shipment delays because packages that normally remain within local sorting hubs tend to be redirected into long-distance transit routes, eventually congesting regional distribution centers. When a routing override system, which counteracts certain effects of the protocol, is implemented along with the protocol, shipment delays occur far less frequently. Therefore, the routing override system probably disables the mechanism by which the protocol causes packages to be redirected into long-distance transit routes.
Which of the following is an assumption on which the argument depends?
A. The routing override system does not directly remove packages once they have entered long-distance transit routes.
B. Factors other than the redirection of packages into long-distance transit routes can cause shipment delays.
C. The routing override system does not reduce overall delivery efficiency.
D. For logistics networks, increased shipment delays are the most harmful effect of using the routing protocol.
E. Distribution networks in which the routing override system but not the routing protocol is used are no more likely to experience shipment delays than networks in which neither system is used.

When a routing override system, which counteracts certain effects of the protocol, is implemented along with the protocol, shipment delays occur far less frequently. Therefore, the routing override system probably disables the mechanism by which the protocol causes packages to be redirected into long-distance transit routes.
Conclusion of the argument:
the routing override system probably disables the mechanism by which the protocol causes packages to be redirected into long-distance transit routes
Supporting premise:
When a routing override system, which counteracts certain effects of the protocol, is implemented along with the protocol, shipment delays occur far less frequently.
We see that the reasoning of the argument jumps from the fact that delays occur less frequently when the override system is implemented to the conclusion that the override system works in a particular way, by disabling the mechanism by which the protocol causes packages to be redirected into long-distance routes.
Which of the following is an assumption on which the argument depends?
The correct answer to this Assumption question will state something that must be true for the premise to effectively support the conclusion.
A. The routing override system does not directly remove packages once they have entered long-distance transit routes.
This choice is interesting.
As discussed above, the argument jumps from the fact that delays occur less frequently when the override system is implemented to the conclusion that the system works in a particular way, by disabling the mechanism by which the protocol causes packages to be redirected.
What it assumes is that the system works in that particular way, and not in some other way, such as by directly removing packages once they have entered long-distance routes.
After all, if the system does directly remove packages from those routes, then it may reduce delays not by disabling the mechanism that redirects packages but rather by removing packages after they've been redirected.
So, this choice has to be true for the argument to work.
Keep.
B. Factors other than the redirection of packages into long-distance transit routes can cause shipment delays.
This weakens the argument rather than states an assumption.a
After all, if there are factors other than redirection of packages that can cause delays, then it could be that the override system reduces delays by addressing factors other than redirection of packages.
Eliminate.
C. The routing override system does not reduce overall delivery efficiency.
The conclusion of the argument is not about overall efficiency. It's about how exactly the override system achieves reductions in delays.
Even if the system does reduce efficiency, the fact that delays decrease when the system is implemented could mean it disables the mechanism that redirects packages.
So, this doesn't have to be true for the argument to work.
Eliminate.
D. For logistics networks, increased shipment delays are the most harmful effect of using the routing protocol.
The point of the argument is not that the system addresses "the most harmful effect."
So, the argument works regardless of whether this is true.
Eliminate.
E. Distribution networks in which the routing override system but not the routing protocol is used are no more likely to experience shipment delays than networks in which neither system is used.
The point of the argument is specifically that the override system reduces in a particular way delays caused by the routing protocol.
The point is not that the override system itself would not cause delays in cases in which the routing protocol is not used.
So, this choice doesn't have to be true for the argument to work.
After all, even if there are more delays when the override system is used in networks in which the routing protocol is not used, it remains the case that there are fewer delays in networks in which the protocol is used when the override system is also used.
Eliminate.

Therefore, the routing override system probably disables the mechanism by which the protocol causes packages to be redirected into long-distance transit routes.
Which of the following is an assumption on which the argument depends?
The argument says delays decrease when the override system is used, so the override probably stops the protocol from redirecting packages into long-distance routes. The assumption is that the override is not reducing delays in some later, different way, such as fixing the problem after packages have already been redirected.
A. The routing override system does not directly remove packages once they have entered long-distance transit routes.
This is correct. If the override simply removes packages after they enter long-distance routes, then delays could decrease even though the protocol’s redirection mechanism is still operating. So the argument needs to rule out this alternative explanation.
B. Factors other than the redirection of packages into long-distance transit routes can cause shipment delays.
This is not required. The argument is about this protocol’s delays, not all possible causes of delays.
C. The routing override system does not reduce overall delivery efficiency.
This is irrelevant. The conclusion is about how the override reduces delays, not about its overall efficiency.
D. For logistics networks, increased shipment delays are the most harmful effect of using the routing protocol.
This is not required. The argument does not need delays to be the worst effect of the protocol.
E. Distribution networks in which the routing override system but not the routing protocol is used are no more likely to experience shipment delays than networks in which neither system is used.
This is not required. The argument concerns what happens when the override is used with the protocol.
