NASA’s Nuclear Frontier: The Plum Brook Reactor Facility
There are three main types of nuclear reactors: power, research, and test. Research and test reactors as scientific tools are more common than most people realize. While power reactors frequently appear in newspaper headlines and are conspicuous because of their size and power, research reactors can be quietly tucked away, even in the midst of a college campus. Power reactors generate heat, which can easily be converted to other useable forms of energy, such as electricity. Research reactors operate at very low thermal power levels – so low, in fact, that they do not even require any type of forced cooling. They are used to measure nuclear parameters and other characteristics, which can then be used to build other reactors or to design experiments for test reactors. Test reactors are more powerful than research reactors and are able to produce much more intense radiation fields. Though they are still much less powerful than the power reactors, they generate enough heat to require a closed-loop forced-circulation coolant system. This system will remove the heat from the reactor by transferring it to a secondary cooling system, which releases it into the atmosphere through cooling towers.

Her boeuf isn't with the delectable spread's chocolate or hazelnut components, but with the fact that it contains palm oil. Demand for this commodity has driven destruction of tropical forests around the world, especially in Oceania. (From NEWSWEEK, 17/06/2015)
According to French Ecology Minister Ségolène Roya
I. When teaching writing to children, telling them that they’ll have an audience is not very important. II. The easiest activity to teach is reading, because the strategies are well known by children. III. Grammar concepts are better understood when taught separately, apart from texts.
Which ones are INCORRECT?
I. Without affecting the meaning, it could be adequately replaced by ‘and then’. II. It is classified as a conjunction. III. It could be removed without affecting the meaning.
Which ones are INCORRECT?
I. ‘them’ (l.32) refers to ‘This process’ (l. 31). II. ‘we’ (l.36) refers to ‘all learning styles’ (l.36). III. ‘them’ (l.40) refers to ‘grammar concepts’ (l.39). IV. ‘they’ (l.40) refers to ‘Children’ (l.39).
Which ones are correct?
“Pupils can choose from an exciting array of reading material” (l.26-27).
I. ‘can’ could be replaced by ‘are going to’ without affecting the meaning. II. The question form of the sentence is “Do pupils can choose from an exciting array of reading material?”. III. To form a negation, you only need to insert the word ‘no’ after ‘can’.
Which ones are INCORRECT?
I. Replacement of ‘purpose’ (l.10) by ‘intention’. II. Omission of ‘explicitly’ (l.17). III. Replacement of ‘stick’ (l.37) by ‘thrust’.
Which ones are correct?
