Two types of fuels, Bio X and Bio Y, both made from natural resources,

proabhinav Greetings Abhinav , please see if this helps

argument : "Since both the government and the people of the country are determined to bring down the pollution levels in the long run," ..
Determined : a very strong word which shows that people are really firm on reducing pollution. If there are certaain concerns where the public would discount their determination then the authro would not have used the word "determined" . There are rare instances when the aurthor makes such strong comments . Also logically , the argumnet wouldnt be much of use if there wouldt have been "determined", as the moemnt we read that therer is aplan we may sya that public will oppose or dislike it so theree isnt mucha strong argument,unless we add "determined "
additionally, you challenged the premise. "people are determined" is not the author's opinion but this is a true fact as in it is infact the case . If the argument said , there is a POSSIBILITY / the governemnt THINKS /the survey THINKS that the people are determined then you could cahllenge the opinion becasue in this case ,the opinion may not be a fact.
Secodnly , you cannot challenge " government THINKS" , WE KNOW FOR A FACT THAT THE GOVERNMENT THINKS, BUT WHAT THE GOVT. THINKS may not be a fact.

Whenever you tackle CRs the first thing before even looking at the question is try to know what are the premises (cannot be challenegd), opinions and conclusion.
The most common wrong answer choices
: 1)opposite (exactly the opposite to whatwe want..for eg: we want a weaknener but the ans choice gives us a strengthener)
2) one word wrong (in this ans choice one single word spolies the choices...and more often that one wprd is at the end ..why?? as we are time bound in exam, we will try to read the first few words and when we think this matches to what we wwant we are in the trap, as we did not read the entire thing.
3)emotional (in this case, the answer choice tries to exploit our meotions or knowledge about something..for eg:if the author is talking about climate change and factors affecting it and concludes that nature is responsble for climate change and not human, we may completely forget about the concklusion and fall for this ans choice becasue we know that it is the humans an not nature that is responsible)

please ask further if you still have any doubts.

Two types of fuels, Bio X and Bio Y, both made from natural resources, are increasingly being used by vehicles around the country( FACT).

Recent tests indicate that the complete combustion of a volume of Bio Y releases fewer pollutants in the air than the complete combustion of an equal volume of Bio X (FACT)
but he complete combustion of a volume of Bio Y releases fewer pollutants in the air than the complete combustion of an equal volume of Bio X (opinion oF test Report)

. Since both the government and the people of the country are determined to bring down the pollution levels in the long run
(FACT)

, it can be expected that in 30 years from now, a significant number of cars will use only Bio Y (Opinion).

Always rmbmr Facts can never be challenged, but opinion can be challenged/refuted.

Always attack conclusion/Opinions but never attack Fact

Thank You, this is helpful.

------------------
C talks about profit margin which is out of scope. Comparison of BioX and BioY is not about money. Hence eliminate C

Knowing that the profit margin for cars running on Y is greater than that of cars running on X is not enough to conclude that most cars will be running on Y in the future. What if car manufacturers received huge incentives from the government for making cars that run on Y? Then, a higher profit margin on X cars might not incentivize car manufacturers to make/sell X cars.

Moreover, you have to make too many assumptions to conclude that C is the correct answer. If you find yourself making assumptions to convince yourself that an answer choice is correct, it is likely that the answer choice is incorrect.
