Solution

Sentence Analysis

  • Because many of Australia’s marsupials, (Dependent Clause modifying the main verb – Subject: Many of Australia’s marsupials)
    • such as the koala, (Provides an example of Australia’s marsupials)
  • are cute and cuddly, (Verb: are)
  • as well as being biologically different than North American marsupials, (Needs to be parallel to ‘cute and cuddly’)
  • they have attracted a lot of attention after their discovery in the 1700s. (Main Clause. Subject: they; Verb: have attracted)

The sentence says that many of Australia’s marsupials have attracted a lot of attention because of two reasons:

  1. They are cute and cuddly.
  2. They are biologically different from North American marsupials.

The sentence has the following problems:

  1. “being biologically different” is not parallel to “cute and cuddly”. We need an adjective to be parallel to “cute and cuddly”. The verb-ing (being), which will become a progressive verb with ‘are’, distorts the parallelism.
  2. ‘different from’ is a preferred construction over ‘different than’, especially when a noun follows ‘different from’. However, when a clause follows (e.g. He is different than I expected him to be), ‘different than’ structure is used since we need a noun phrase or a noun-clause to follow ‘different from’.
  3. The present perfect verb ‘have attracted’ doesn’t align with the word ‘after’ since present perfect tense indicates an action that has continued from sometime in the past to the present whereas ‘after’ is used to indicate the time of a single event with respect to an earlier event.

Option Analysis

(A) Incorrect. For the reasons mentioned above.

(B) Incorrect. For the following reasons:

  1. Error 1 of the original sentence
  2. Simple past tense ‘attracted’ doesn’t go with ‘since’. We need present perfect tense to go with ‘since’.

(C) Incorrect. For the following reasons:

  1. Problem no. 2 of the original sentence
  2. Problem no. 2 of option B

(D) Incorrect. For the following reasons:

  1. Problem no. 2 of the original sentence
  2. Problem no. 3 of the original sentence

(E) Correct.
