If the current attitude continues, daily life on earth will be significantly affected by pollution from both the industrial and domestic sectors.


A. will be significantly affected

B. could be significantly affected

C. is affected

D. will significantly affect

E. would be significantly affected



OFFICIAL EXPLANATION



If the current attitude continues, daily life on earth will be significantly affected by pollution from both the industrial and domestic sectors.


A. will be significantly affected

This question begins with the condition part of a conditional sentence (If... continues). This part is in Present, which means that the conditional is Conditional 1. The underlined part is the result part. The result part of Conditional 1 sentences should be in Future or Present, as is the case in this answer choice.

What helps identify this question as a Conditionals question is the following Stop Sign:

    If / Unless



B. could be significantly affected

This answer choice is grammatically incorrect. The question begins with the condition part of a conditional sentence (If... continues). This part is in Present, which means that the conditional is Conditional 1. The underlined part is the result part. The result part of Conditional 1 sentences should be in Future or Present. This answer choice, however, uses Past (could).

What helps identify this question as a Conditionals question as well as identify the mistake is the following Stop Sign:

    If / Unless



C. is affected

This question begins with the condition part of a conditional sentence (If... continues). This part is in Present, which means that the conditional is Conditional 1. The underlined part is the result part. The result part of Conditional 1 sentences should be in Future or Present. While this answer choice is grammatically correct, the omission of the word significantly changes the meaning of the original sentence.

What helps identify this question as a Conditionals question is the following Stop Sign:

    If / Unless



D. will significantly affect

This question begins with the condition part of a conditional sentence (If... continues). This part is in Present, which means that the conditional is Conditional 1. The underlined part is the result part. The result part of Conditional 1 sentences should be in Future or Present.

What helps identify this question as a Conditionals question is the following Stop Sign:

    If / Unless

While this answer choice is grammatically correct, the transition from passive (be affected) to active changes the meaning of the original sentence. This change also produces an illogical sentence. Finally, this answer choice doesn't fit into the original sentence.



E. would be significantly affected

This answer choice is grammatically incorrect. The question begins with the condition part of a conditional sentence (If... continues). This part is in Present, which means that the conditional is Conditional 1. The underlined part is the result part. The result part of Conditional 1 sentences should be in Future or Present. This answer choice, however, uses Future-Past (would be).

What helps identify this question as a Conditionals question as well as identify the mistake is the following Stop Sign:

    If / Unless
