Critical Reasoning

With a record number of new companies starting up in Derderia and with previously
established companies adding many jobs, a record number of new jobs were created
last year in the Derderian economy. This year, previously established companies will
not be adding as many new jobs overall as such companies added last year. Therefore,
unless a record number of companies start up this year, Derderia will not break its
record for new jobs created.
Which of the following is an assumption on which the argument relies?
A. Each year, new companies starting up create more new jobs overall than do
previously established companies.
B. Companies established last year will not add a greater number of jobs overall
this year than they did last year.
C. This year, the new companies starting up will not provide substantially more
jobs per company than did new companies last year.
D. This year, the overall number of jobs created by previously established
companies will be less than the overall number of jobs lost at those companies.
E. The number of jobs created in the Derderian economy last year was
substantially larger than the number of jobs lost last year.


Please explain options A,B and C

i understand that d and e are out as they talk about the number of jobs lost

also as per my analysis b is restating the fact from the argument

So the tussle is between C and A. B I agree is a restatement.

We can negate C and the argument falls apart.

However A is nebulous territory, can not fully apply the negation test but if I go to the basics ...........Assumption is an unstated premise and plug A in so that it supports the argument, I see that the argument may or may not hold. For example if last year 45 Jobs created by start ups and 35 by old cos, this year old cos provide 25 and start ups 27 and let us assume that more start ups opened (thus average of jobs provided by start ups declined), the argument still does not hold or get supported.

Thus I would go with C, which clearly undermines the argument if negated.

What is the OA?

Last year - Group A ( Previously established companies) + Group B (New Companies)

Both Group A and Group B contributed to a record number of new jobs.

This year - Group A ( Previously established companies) + Group B (Last year New Companies) + Group C ( New companies)

(Note : This year, we can't assume that last year newly added companies will become previously established companies)

Now, per stmt, "previously established companies will not be adding as many new jobs overall as such companies added last year" --> So the best possible scenario is that Group A creates same number of jobs or less.

Per stmt, "unless a record number of companies start up this year" --> So to break last year record, Group C needs to add more jobs overall.

Hence, we can expect some assumption about Group B. Answer choice B states that. In negation testing, " Companies established last year will add a greater number of jobs overall this year than did last year". If this is true, then the conclusion falss apart since we no longer need record number of new companies created this year to create job.

IMO B

I will go with 'B'. Pls post OA.

IMO B. When I prephrased answer, I was looking for something like option B.

Nice explanation ,
crucial point is
(Note : This year, we can't assume that last year newly added companies will become previously established companies)

But what is the official answer????????????

ok it is official the answer is C

Got it from Phil (pm)

Thanks Phil

not satisfied with C.

Unless a record number of new companies open.... derdaria will not break ...

or

if a record number open... derdaria will break..

then the assumption would have been-
the new companies will create more jobs than they did last year

The option given is that they will not. Which is actually weakening the argument. I still stick with B.

Please tell me why the above reasoning is incorrect.

suspicious OA... imo B

Stimulus says that (i) Established companies will NOT be adding as many jobs as last year (=deficit) (ii) Expects record number of startups to cover deficit plus add high number of jobs to the overall job numbers this year.
Conclusion is that deficit will not be covered and the country D will not have a record number of jobs created.

A - If New co.s create more jobs than established co.s every year, then maybe they can cover the deficit and create a record number. So this would negate the stimulus's argument.
B - is a restatement of "previously established companies will not be adding as many new jobs overall as such companies added last year". Words are just moved around.
C - "will not provide ". This assumption assures that deficit will not be covered by newer companies creating more jobs than new companies of last year. Hence the right assumption supporting the conclusion.
