STEP 1 - UNDERSTANDING INTENDED MEANINGIn the 1980s, climate change warmed the Gulf of Maine’s cool waters to the ideal temperature for lobsters, which helped Maine’s fishery grow fivefold to a half-billion-dollar industry, however, it will eventually increase the temperature to a level unsuitable for the lobsters to thrive.Errors: 1. Here
“which” is referring to the action/verb “warmed”. The climate change warmed the waters and this action helped Maine’s fishery. “Which” cannot be used to refer to a verb.
2.
“However” should be preceded by a semi colon to separate the two independent clauses and make the construction grammatically acceptable.
Intended meaning:• In the 1980s, climate change warmed the Gulf of Maine’s cool waters to the ideal temperature for lobsters.
• This warming of the cool waters helped Maine’s fishery grow fivefold to a half-billion-dollar industry.
• However, the same warming of the cool waters will eventually increase the temperature to a level unsuitable for the lobsters to thrive.
STEP 2 - ELIMINATE CHOICES WITH IDENTIFIED ERRORSThe following choice/s have one or more of the errors present in Choice A.
Choice B – no semi – colon before “however”
STEP 3: EVALUATE MEANING OF REMAINING CHOICESChoice C
In the 1980s, climate change warmed the Gulf of Maine’s cool waters to the ideal temperature for lobsters,
and helped Maine’s fishery grow fivefold to a half-billion-dollar industry, but will eventually increase the temperature to a level unsuitable for the lobsters to thrive.
• The use of “but” indicates a contrast. Also, the use of “but” requires that the subject of the verb be repeated after the “but”
• What will increase the temperature? – climate change
Incorrect Choice.Choice D
In the 1980s, climate change warmed the Gulf of Maine’s cool waters to the ideal temperature for lobsters,
helping Maine’s fishery grow fivefold to a half-billion-dollar industry, but it will eventually increase the temperature to a level unsuitable for the lobsters to thrive.
• “Helping” preceded by a comma is correct modifying the verb “warmed”
• The use of “it” after the “but” makes the sentence clear and logical.
1. Logical
2. Clear
3. Same as the intended meaning
Correct Choice.Choice E
In the 1980s, climate change warmed the Gulf of Maine’s cool waters to the ideal temperature for lobsters,
helping Maine’s fishery grow fivefold to a half-billion-dollar industry, but eventually increasing the temperature to a level unsuitable for the lobsters to thrive.
• “helping”….but …”increasing” look parallel but both the things could not have happened at the same time.
• The climate change could not have helped and harmed simultaneously.
• First the climate change warmed the waters
• But this warming will ultimately be harmful.
Incorrect Choice.
