Let’s break the sentence down

1. Green taxes charge a a price for the use of polluting or nonrenewable fuels
2. The above fact has a positive effect on the environmental and natural resource base of countries
3. The countries the above statement talks about are varied (diverse). Examples of such countries are given

Since China, Netherlands and Hungary are examples of varied countries where green taxes have a positive effect, “as varied as” will suffice and option A is the correct answer.

Distinguish their own species from others – The others here refers to other species

Example:

I am able to distinguish a good book from bad ones – Ones refers to books

I am able to distinguish a good book from that/those of bad ones – Incorrect. What does the that/those refer to?

Also, those of others’ is redundant. Those of indicates possession and others’ with the apostrophe after s also indicates possession (of others)

Hi Nikita,

There are 2 problems with option D

Projects X to do Y is unidiomatic. Projects ‘NOUN’, or projects that X will do Y’ both are correct constructions
An average is a single data point, so average from 1.8 to 6.3 is incorrect. A single data point can fall between two given values (as in option E)

E is the correct answer choice

Consider the following 3 sentences:

1. I didn’t like the new restaurant, but I liked the other restaurants in the locality – Correct
2. I didn’t like the new restaurant, but I liked other restaurants  in the locality, such as X and Y – Correct
3. I didn’t like the new restaurant, but I liked the other restaurants  in the locality, such as X and Y – Incorrect. “The” and “such as” cannot be used this way. You either say you liked the other restaurants which means you liked every other restaurant in the locality or you give specific examples of restaurants you liked using “such as”

Hi Nikita,

The construction is similar to that in “I attended the school’s annual day celebration as the chief guest”. Here, when I say as the chief guest, I mean in the capacity of chief guest. It would be incorrect to say “I attended the school’s annual day celebration as the chief guest did”. That means I am trying to impersonate the chief guest / at the same time

Hi Manoj,

Option E is unnecessarily wordy. It says “with the exception” “with the staging”. The intended meaning gets lost in this contruction

Option A is is very clear and concise. The “that” correctly refers to concert performance and the meaning of the sentence is very clear

Hi Manoj,

“Delighted by the reported earnings for the first quarter of the fiscal year” is a modifier and the rule for such a modifier before a clause is that whatever noun the modifier modifies has to immediately follow the modifier.

In this case, who was delighted by the reported earnings for the first quarter of the fiscal year? The manager. Hence, the manager has to immediately follow the modifier. Hence option C is the correct answer

Hi Manoj,

(A) sprang to life not in a flash of inspiration but evolved slowly – The contrast should be between “sprang to life” and “evolved slowly”. In this option, the contrast is between “flash of inspiration” and “evolved slowly”. Hence incorrect

(B) sprang to life not in a flash of inspiration but were slowly evolved – The contrast should be between “sprang to life” and “evolved slowly”. In this option, the contrast is between “flash of inspiration” and “evolved slowly”. Hence incorrect

(C) did not spring to life in a flash of inspiration but evolved slowly – Correct contrast. No other errors in grammar or meaning

(D) did not spring to life in a flash of inspiration but had slowly evolved – “had evolved” is past perfect tense. Past perfect tense is only used when there are 2 past events on the timeline. It is unnecessary here. . Hence incorrect

(E) did not spring to life in a flash of inspiration but they were slowly evolved – “They” is ambiguous since it can refer to both papers and inventions

Hi Nikita,

This doesn’t seem to be an official question. The answer option C isn’t clear. Can you please check the answer options?

Based on what I could understand from the way C is worded, it doesn’t matter whether customers buy all the 10 gallons of gasoline in one go or buy smaller quantities more frequently. All that matters is whether or not they bought 10 gallons

Hi Nikita,

You need to find an assumption on which the experts’ conclusion relies.

The experts’ conclusion: Among members of the general population who have spent a similarly large amount of time in close contact with animals, the percentage with animal-induced allergies is substantially more than 30 %

Why the conclusion? Because in a survey of current employees in major zoos, about 30 percent had animal-induced allergies

You need to find something that connects the above 2. Option A says a zoo employee who develops a serious animal-induced allergy is very likely to switch to some other occupation. If this is the case, then the zoo employee who has already developed allergy becomes part of the general population and adds to the number of people with allergy. Hence A is the assumption the experts are making in saying that the percentage among general population is more than 30.

B is incorrect because the source of allergy doesn’t matter. Regardless of whether the zoo employee gets affected by home pets or by zoo animals, he develops allergy. However in both cases, the zoo employee is counted as a zoo employee only and not as a member of general population and also he/she is counted only once and hence option B doesn’t explain how the percentage is higher in case of general population.
