The construction here is COMMA + for example. In this construction, the example must PRECEDE for example. To illustrate: Over his lifetime, John has taken many tests. He recently took the GMAT, for example. Here, the example is the GMAT, the noun preceding COMMA + for example. In E, the example is the noun following COMMA + for example: a hydraulic dredge. This construction is not viable. A caveat: Typically, COMMA + for example serves to support a PRECEDING SENTENCE. In my two sentences about John, COMMA + for example refers to the GMAT -- an example that supports the preceding sentence (John has taken many tests). On the GMAT, each SC must be self-contained; there are no preceding sentences. For this reason, I would be skeptical of any answer choice that employs COMMA + for example.
