Choose the wrong part of the sentence

Greetings, this question is in a TOEFL test practice exam.

Water levels in the great lakes (fluctuate dramatically)1 over periods of years (by as much as one meter)2, and during the spring runoff, the level (may rise and fall)3 by as much as two meters particularly in lake Erie, (the shallow of the five)4.

Please add grammatical explanation.

First we need to know what you think the wrong part might be.

 

[finix33]

Well I think it's number 2. The word much should be many, because meter is a countable noun.

Am I correct?

 

[MikeNewYork]

No, that part is correct. Have a look at number 4.

 

[finix33]

No, that part is correct. Have a look at number 4.

Is it a reduced adjective clause in a place where it shouldn't be reduced?

 

[MikeNewYork]

No. The word "shallow" should be "shallowest".

 

[finix33]

No. The word "shallow" should be "shallowest".

Oh!! :-D that was a tricky one thank you.

"Great Lakes" should be capitalized, as should "Lake Erie."
