Patricia, clearly you can read, but I fear you would fail in the old-fashioned skill of Comprehension tests, which require you to read a passage and draw fair inferences. Read the passage again and you might see that the OP starts by setting out his desire to join an MBBB firm, BUT recognising the stringent entry criteria, fears that he may have to settle for a “smaller shop”. This is a clear recognition on his part that they are not the same thing.He then goes on to immediately question this strategy by questioning whether it is feasible to start in a small shop and then progress to “EVEN” a big4 firm (my capitalisation for emphasis). The use of the word even is another clear indication that the OP recognises that big4 are not the same as MBBB, but would be a progression from a “small shop”e.g. I would love to play for Chelsea but suspect I would not EVEN get a trial for Scunthorpe – clear indication to even those not familiar with football that Scunthorpe are generally lower valued than Liverpool.The inference across the piece is clear to anyone who does more than read just the words in their literal fashion.1. The OP believes that MBBB firms have the most stringent application criteria, followed by big4, followed by “smaller shops”.2. The OP questions his own hypothesis that one might gain entry to a lower level of this hierarchy and then progress on the basis of experience earned when direct entry would have been impossible.Perhaps the lack of information that you managed to derive from the passage explains your lack of appreciation of literature, expressed elsewhere.
