Conclusion: Offices should choose inkjet because they'll have fewer workflow disruptions
Evidence compares servicing rates
Assumption: The higher servicing rates for laser printers is not simply becasue they are used much more heavily

A. Print quality is irrelevant
B. This is required Assumption
C. Number of offices surveyed is irrelevant
D. Downtime per service: Even if laser service takes longer, the argument is based on servicing frequencies.
E. it is irrelevant

Hence, B

A: Since the question is concerned with 'uninterrupted use' lower quality may or may not be a hindrance.
B: Higher print volume would mean faster wear and tear. Hence, this assumption strengthens the argument and is critical for it to hold up.
C: Since we are talking percentages, the exact number is immaterial
D: If we assume that laser printers do NOT generally require longer downtime, that does not change the fact that they broke more in the first place. And if they even ocassionally require longer downtime, that makes the situation worse.
E: Again, since the laser printers broke down more in the past year, if they were acquired after inkjet, that makes the case for laser printers worse.

Since B is a critical assumption for the argument to hold up, 'B' is the answer.

A - The print quality of the document is not part of the argument, the uninterrupted flow is
B - Correct. This provides a possible reason on why laser printers need more servicing than inkjet, which undermines the argument that the company should go for inkjet since they're being subjected to much less work than the laser printers
C - Since we're talking in percentages, the absolute number of printers acquired does not matter
D - If anything this undermines the argument that the laser printer need similar or less servicing time, Also, duration of the service is also out of scope for this argument
E - The liklihood of acquiring a certain type of printer does not affect the argument

Assumption: Offices that depend on uninterrupted printing should expect fewer disruptions by choosing inkjet over laser printers.

A) We are not concerned about the print quality but the number of disruptions -> Irrelevant = INCORRECT
B) If true, then we have an alternative reason for the lower service requirements of the inkjet printers. Choosing inkjet over laser printers to minimise disruptions therefore depends on how frequently you use them. For the argument to hold, it has to assume this isn't the case and thus makes the assumption -> CORRECT
C) The percentage of printers requiring servicing is a relative measure -> INCORRECT
D) The Assumption pertains to inkjet printers experiencing fewer disruptions, so the length of downtime actually isn't relevant. Also, even if it is true, this would strengthen the idea that inkjet users experience fewer disruptions due to shorter downtimes -> INCORRECT
E) Similar to C. Relative measures are used, we would be making our own convoluted assumption about how age affects service requirement (common trap) -> INCORRECT

We have to find the assumption. A is out of scope, quality is not discussed; C is % trap, D is actually against what the argument would want. Of B and E, E talks about acquisition time which does not directly address the issue.

B makes sense. If the offices are using laser printers way more, their chances of needing servicing increases. B is the answer.

The answer is B). If the laser printers have higher print volumes than inkjets it would be reasonable that they would have a higher percentage that needed servicing. Therefore, to make the claim that offices that want uninterrupted printing should pick inkjet printers relies on the assumption that the offices in the survey had similar printing production for laser and inkjet printers.

A is incorrect because the claim is focusing on business who prioritize uninterrupted printing. The print quality of the two printer options is irrelevant to the claim.

C is incorrect because that assumption is not required to make the claim. It might be tempting to pick because if one printer had a smaller sample size, those percentages might be less reliable, but you could the claim regardless of sample sizes.

D is incorrect. This assumption is not needed for the claim. For this one I thought about the opposite assumption. If laser printers generally required more downtime after servicing and need more servicing than inkjets, this would better for the claim. So to say laser do not generally required more downtime is not a needed assumption for the claim

E is incorrect because it is irrelevant to the claim. Office printer buying patterns are irrelevant to the claim that inkjets are better for offices that want uninterrupted printing.

(A) Print quality has no connection with the frequency of the servicing - Irrelevant.
(B) Negating this weakens the argument. If the volume of prints processed using Laser Printers is more than the high servicing rate could be due to heavy usage rather than low reliability. - Correct
(C) The comparison uses % and so the number of offices does not matter - Irrelevant.
(D) The argument is about the frequency and not the duration - Irrelevant.
(E) When the printers were purchased does not affect whether one type requires more frequent servicing. - Irrelevant.

The assumption here is the same volume of printing is supported/ needed from both the printing we are looking at only repairs but it could be highly possible that the might have been more in use of laser printing than ink printing.

B. It assumes that the quantity of print is same using either of the printers. So, disruption is more in laser.

I got B as the answer. If laser printers were used as frequently as inkjet printers and even then the servicing % was higher, then choosing inkjet printers over laser printers make more sense.

i am going with option b.
as option b states that both the types of printers are used for similar volumes as if it wasn't assumed we can argue that laser printers are reliable but are breaking down due to significant use of printing volume so if we assume that it isn't the case then we can conclude that both the types of printers are used similarly and that inkjet is reliable for undisrupted access for printing than laser which is generally ineffective and can reach our conclusion.

The argument assumes that both laser and inject printers are used the same amount. Perhaps the inject printers will have higher servicing requirement if used as often as laser printer. Option B is correct.

The assumption here is that both inkjet and laser printers are in use at the same rate. Because if the author takes into account the usage rate of both type of writers in analysis, it wouln't have concluded a straight-forward replacement with the other option.

[PREMISE]
Out of new printers acquired.
1. twelve percent of laser printers in use had needed servicing on more than one occasion
2.just three percent of inkjet printers that had ever required any servicing at all.

[CONCLUSION]
Offices that depend on uninterrupted access to printing should therefore expect far fewer workflow disruptions by choosing inkjet over laser printers.

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

We do not necessarily know if lower quality of print would disrupt workflow. And has nothing to do with serviceability
Therefore eliminated.

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.

If this option is negated then our conclusion does not hold true.
CORRECT

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

This is very close.
Lets negate this

many offices in the survey had [NOT] acquired laser printers as had acquired inkjet printers.

This means far few offices had laser printers than inkjet printers.

Does this Break our conclusion
"Offices that depend on uninterrupted access to printing should therefore expect far fewer workflow disruptions by choosing inkjet over laser printers" ??

It actually strengthens the conclusion EVEN FURTHER.

therefore, eliminated.

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

Negating this,
Laser printers do generally require longer periods of downtime for each service visit than inkjet printers do.

AGAIN, strengthens the conclusion.
Therefore, eliminate.

E) time of acquisition is not necessarily relevant.

C because in order for the percentages to be comparable their bases have to be same or very close .

12% LP needed servicing and 3% IP needed any servicing.
Conclusion: offices should choose IP over LP to experience fewer workflow disruptions.

A) the argument is not about the quality of the print.......Wrong
B) if Laseer printers are used at significantly higher volumes, a higher service rate might be expected, simply due to wear & tear due to high usage. Maybe if they use in jet printers in higher volumes then the percentage of their servicing might also increase. Hence, for the argument to hold, we must assume that the difference in service rate is due to technology and not because laser printer are being used significantly more than inkjet printers. ................. Correct
C) Numbers does not affect the validity of comparison in survey.............Wrong
D) the argument is about the frequency of servicing and not about the duration of servicing.........Wrong
E) it is about the timeframe of the acquisition and does not affect the argument......Wrong

B

office managers were surveyed.
found that those in last 5 years who had adopted laser printers, 12% of laser printers had needed more than one time servicing.
whereas those with inkjet printers, only 3% required any servicing at all.

conclusion = if offices depend on uninterrupted access to printing, they should expect fewer workflow disruption by choosing inkjet over laser printers.

here need of service has been associated with workflow disruption. more percent of laser printer require service so they concluded that by choosing inkjet, fewer disruption will happen. but what if servicing doesnt affect the workflow?

A not concerned about print quality here. out.
B that means despite not operating at higher volume, they needed more servicing then it make sense not to go with laser and go with inkjet. but if negate then it means laser printers are operating at higher volume so definitely need more servicing, then conclusion breaks down. keep.
C means the office num are same but that doesnt provide any missing link for the conclusion. out.
D if laser doesnt require longer downtime then the conclusion doesnt make any sense of saying thaty there will be fewer disruption by going with inkjet. in this case offices can go with laser despite the fact that more offices had servicing. so this is wrong.
E this is irrelevant comparison here. out.

Choice B
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.
