Which option represents the correct version of the underlined portion of the sentence?

    NO CHANGE
  2. B
    more effective then those of his predecessor
  3. more effective than those of his predecessorAnswer
  4. D
    more effective than, those of his predecessor,

Answer

The option containing 'more effective than those of his predecessor' is the correct answer.
The correct option is 'more effective than those of his predecessor' because it correctly compares the policies of one president to the policies (represented by 'those') of another. It also uses 'than' for the comparison rather than 'then' and has no unnecessary punctuation.

Step-by-Step Solution

1
Identify the items being compared.
The sentence compares 'President Alvarez's policies' with 'his predecessor's policies'.
A comparison must compare logically equivalent items. Comparing 'policies' to 'a person' is illogical.
2
Select the correct comparative word and spelling.
Use 'more effective than' because two items are being compared and 'than' is the correct spelling for comparative relationships.
'Then' denotes time or sequence, whereas 'than' is used for comparisons.
3
Evaluate the punctuation and pronouns.
Use the pronoun 'those' to represent 'policies' and avoid inserting unnecessary commas.
The correct phrase is 'more effective than those of his predecessor' without any commas around it.
