A Print quality is outside the scope of this specific logical link.

B The author is assuming both types of printers are being worked at roughly the same intensity. He must assume this massive difference in workload is not happening. Correct answer.

C The total number of offices that bought each type of printer does not matter. The survey relies on percentages.

D The author doesn't need to assume the repair time is short. Even if lasers take ages to fix, it just proves the author right that inkjets are the better choice to avoid disruptions.

E It is an irrelevant detail about shopping timelines.

The answer is B

Here, we need to first identify the conclusion or main argument of the passage: Offices that need uninterrupted access to printing, should expect less disruptions from inkjet printers. Now, what would lead this conclusion to break down? If the inkjet printers in the survey were used far lesser than laser printers, they would naturally not need as much servicing. Option B illustrates this. Note that the total numbers does not matter here, because we are not talking about absolute numbers of inkjet or laser printers, but percentages, which account for the total number of printers of each type in the survey.

Bunuel
A survey of office managers who had acquired new printing equipment over the previous five years found that twelve percent of laser printers in use had needed servicing on more than one occasion, compared with just three percent of inkjet printers that had ever required any servicing at all. Offices that depend on uninterrupted access to printing should therefore expect far fewer workflow disruptions by choosing inkjet over laser printers.

Which of the following is an assumption the argument relies on?

(A) Inkjet printers do not produce noticeably lower print quality than laser printers for standard office documents.

(B) Offices that use laser printers are not far more likely to operate them at substantially higher print volumes over time than offices that use inkjet printers.

(C) At least as many offices in the survey had acquired laser printers as had acquired inkjet printers.

(D) Laser printers do not generally require longer periods of downtime for each service visit than inkjet printers do.

(E) Offices that acquired printing equipment within the past year are not far more likely to have chosen laser printers than offices that acquired equipment five years ago.

One of the key assumptions here is the usage is same. If the inkjet printers are not used as much, and that's the reason they require less repair, then we can't draw the same conclusion as drawn by the author. Hence, this is a key assumption.

A. The conclusion doesn't focus on quality. Hence we can eliminate this option.

B. This is inline to our pre thinking. Hence, we can keep this. Negating this statement will break the argument, as the focus now changes and tells us why lasers printers require more servicing.

C. This is not required for the conclusion to hold true. Because, the percentage factor takes care of the number. Eliminate C.

D. Well this is quite opposite to the what we are trying to conclude. If lasers printers do require longer downtime, its wiser to switch to inkjet printers. Not an assumption. D can be eliminated.

E. Not a required assumption. Even if more laser printers are purchased, given we are referring to percentage the comparison is uniform.

Option B is the correct one.

A Print quality is irrelevant. The argument is only about workflow disruptions from servicing.

B CORRECT. The argument assumes that the difference in servicing rates reflects the printers' reliability, not some other factor. A major alternative explanation is usage.

C The relative number of laser and inkjet printers in the survey doesn't matter. Percentages are being compared.

D Longer repair times could affect disruption, but the conclusion can still reasonably follow without assuming equal downtime.

E When the printers were purchased is irrelevant.

The correct answer is B

Numbers to percentages. Just because a percentage is greater doesn't mean that the actual number is greater, we don't know how many inkjet vs laser printers were in use.

Necessary assumption - if it fails, then the argument falls -> negation test.
(A) is irrelevant to the above.
(B) is not the main gap in the argument we identified.
(C) if this option fails, then the argument falls on its face. If the amount of inkjet printers is lower than the laser ones, it weakens, if not destroys the conclusion.
(D) is irrelevant again.
(E) doesn't immediately talks of the absolute number of printers in each group.

Here percentage of Laser printers that required servicing as compared to Inkjet printers is discussed. This comparison is justified when both type of printers are subjected to equal usage. However, if Laser Printer is used for much higher print volumes, then it is highly likely that it will require more service. Hence, option B is the best answer choice.

The argument says offices should choose inkjet printers because they will have fewer workflow disruptions. It assumes the comparison between laser and inkjet printers is fair.

A. Not required. Print quality is not related to service needs or disruptions.

B. Correct. If laser printers are used much more heavily than inkjet printers, the higher service rate could be caused by heavier use, not because laser printers are less reliable.

C. Not required. The number of offices using each type does not affect the conclusion.

D. Not required. The argument is about how often printers need service, not how long each repair takes.

E. Not required. The timing of when offices bought printers does not affect the comparison.

Conclusion of the passage- Offices that need uninterrupted printing can prefer Injkjet printers rather than Laser

The job of a printer is of printing pages and passage tells us that Laser printer was serviced more. Here there is an unstated assumption that both the printers did same amount of work.

If we analyze options according to this , we can select B as the correct option .

The argument concludes that inkjet printers will cause fewer workflow disruptions because they needed servicing less often.
For that to be true, we must assume the higher servicing rate for laser printers isn't simply because they are used much more heavily.

Let's check the options :

A is about print quality. Nothing to do with servicing or workflow disruptions. Eliminate

B sounds right imo. If laser printers are used for much higher print volumes then they would naturally need more servicing. In that case, the comparison wouldn't be fair. Keep

C doesn't matter. The no. of offices using each type doesn't affect the reasoning. Eliminate

D talks about how long each repair takes, but the argument is based on how often servicing is needed, not the duration. Eliminate

E is irrelevant because when the printers were purchased doesn't explain the difference in servicing rates. Eliminate

Ans : B

Survey of office managers who acquied new printing equipment over the previous 5 years found 12% of laser printers needed servicing on more than one occasion, compare to just 3% of inkjet printers that required servicing at all.

Conclusion: - Offices that depend on uninterrupted access to printing should chose inkjet over laser printers to avoid workflow disruptions.

Find assumption (gap)

A. We are not concerned about quality of printing but are concerned with service disruptions. Incorrect

B. If offices that use laser printers are far more likely to operate them at substantially higher print volumes over time than offices than use inkjet printers then the conclusion that replacing laserjet with inkjet printers falls apart since inkjet printers may start giving disruptions when higher volumes are printed.

If assumption is negated, the argument falls apart.

Correct

C. We are not concerned with absolute number of printers in the argument. Incorrect

D. In case laser jet printer require longer period of downtime for each service than inkjet printers do, then the conclusion is strengthened instead of falling apart. Incorrect

E. If offices chose more laserjet printers last year then these printers should not be giving more service disruptions. Incorrect

IMO B

Premise:
New printing equipment by over last 5 years: 12% of LP in use - needed service more than once.
3% of IP - had taken at-least 1 service

Conclusion:
Choose IP for less/no disruption

(A) (E) Not relevant
(B) No - it looks like it S the argument infact!
(C) Yes - as This helps with comparison.
(D) No. It talked about downtime.

The conclusion that offices depending on uninterrupted access to printing should expect fewer disruptions by choosing inkjet over laser printer is based on the survey results that laser printer needs more servicing. If laser printers are used more frequently then the need for servicing is increased, which would help explain the results of the survey.
Hence, B is the assumption for the argument to hold true.

The argument makes a comparison between inkjet and laser printers, making it clear that inkjet printers need less servicing (3%) than laser ones (12%). The conclusion tells us that offices should choose inkjet printers over laser ones if they want fewer disruptions (each disruption is a servicing need). The assumption here would be that to compare two types of printers by their servicing rates, everything else must be equal. That means, for example, good maintenance, equal use, and so on, so we could attribute it to the printer type specifications, and not heavy usage, or bad maintenance. To find the correct answer, we need to find an answer choice that directly tells us about factors that are correlated with the disruptions, servicing, or maintenance.
Let's see the answer choices now:

A - That's great; however, we cannot find any mention of print quality in the argument. This is irrelevant
B - This is the right answer. Now we have information that both laser and inkjet printers are operating at nearly the same volumes. If laser printers operated at higher volumes, the higher servicing percentage might have been attributed to higher usage, but now we know that the conditions and maintenance are equal for both types, which means that it is true that inkjet printers are better (with everything else being equal)
C - The numbers do not matter as long as we have percentages (and as long as they are correct)
D - This assumption favors the laser printers, which is not what we are looking for.
E - Frequency is irrelevant to our conclusion.

Answer: B

Answer is C, the assumption is made that almost same number of laser printers are acquired as the number of inkjet printers.


Bunuel
A survey of office managers who had acquired new printing equipment over the previous five years found that twelve percent of laser printers in use had needed servicing on more than one occasion, compared with just three percent of inkjet printers that had ever required any servicing at all. Offices that depend on uninterrupted access to printing should therefore expect far fewer workflow disruptions by choosing inkjet over laser printers.

Which of the following is an assumption the argument relies on?

(A) Inkjet printers do not produce noticeably lower print quality than laser printers for standard office documents.

(B) Offices that use laser printers are not far more likely to operate them at substantially higher print volumes over time than offices that use inkjet printers.

(C) At least as many offices in the survey had acquired laser printers as had acquired inkjet printers.

(D) Laser printers do not generally require longer periods of downtime for each service visit than inkjet printers do.

(E) Offices that acquired printing equipment within the past year are not far more likely to have chosen laser printers than offices that acquired equipment five years ago.

B should be the correct answer, as if laserjet printers are producing much higher volumes than inkjet comparatively then the high vol might be the reason for it needing more servicing rather than just the difference bw laser and ink, if ink is also used at the same vol might need similar or higher amount of servicing.
A - quality is not in question.
D - downtime is not in question, frequency of servicing is
A/E - only number of printers is not a solid enough point to explain frequency of service/why should one be chosen over the other

I think its B , as the statment say that the laser printer break down 12% in which its one or more time that compare to inkjet which broken down rarely 3% over 5 years time and as we see in answer B) it says that office will not likely to operate laser prineter for higher volume as compare to that of inkjet which if see above is true.

The prompt goes as follows:
  • From laser printers, 12% needed1+ servicings, and from inkjet printers, only 3% needed any service => inkjet printers provide fewer disruptions (break less often).
This makes sense, but only ceteris paribus, if only the actual reliability and no other occurrences or specifications impacted this difference.

A deals with printing quality and not reliability, which is beyond the scope of the argument.

B provides another reason for more frequent breaks of laser printers, which would actually destroy the conclusion by disputing the fact that inkjets are less sure not to break. This seems like the right assumption.

C would only work if we had absolute values compared; however, we already have the relative values (percentages), so the quantitates shouldn't be necessarily matching.

D is irrelevant, since the argument focuses on the fact of a service needed and how many 'attendances' a printer needs, not the duration of individual ones.

E, once again, focuses on the mathematical aspect of comparison and suggests that the number of printers of each type should be comparable - however, we have quite explicit indicators of 3% and 12%, so the 'popularity' of one type wouldn't impact it much.

Therefore, the answer is B.
