The correct stress for the word 'concessionaire' is 'con-cess-ion-AIRE'. The primary stress is on the last syllable.

Explanation

(i) \(2\frac{2}{3} - (2\frac{1}{2} - 1\frac{4}{5})\)

= \(2\frac{2}{3} - (\frac{5}{2} - \frac{9}{5})\)

= \(\frac{8}{3} - (\frac{25 - 18}{10})\)

= \(\frac{8}{3} - \frac{7}{10}\)

= \(\frac{24 - 21}{30}\)

= \(\frac{3}{30} = \frac{1}{10}\)

(ii) \(\frac{3.25 - 1.64}{2.47 - 2.01}\)

= \(\frac{1.61}{0.46}\)

= \(\frac{7}{2}\)

= \(3\frac{1}{2}\)

Correct Answer: C. reduce price

Correct Answer: A. seeing

Explanation

The correct answer is A. seeing.

Explanation:

The phrase look forward to is a phrasal verb where to is a preposition, not part of an infinitive. When to is a preposition, it must be followed by a noun, a pronoun, or a gerund (the -ing form of a verb acting as a noun).

• Looking forward to seeing you (seeing is a gerund) is the correct grammatical construction.

Let's look at why the others are incorrect:

• B. see is the base form of the verb, which would be used after an infinitive to (e.g., I want to see you), but not after look forward to.

• C. have seen is a perfect infinitive or past participle form, which doesn't fit here.

• D. will see is a future tense verb, and you cannot follow a preposition directly with a finite verb like this.

Correct Answer: A. James the brother of John

Explanation

One of the major themes dealt with by Paul in his letters was the second coming of Jesus Christ. He spoke of imminence of the great occasion and the need for Christians to lead a good life in readiness for Jesus at his second coming. Some Thessalonian Christians were led to the misconception that the Parousia was just around the corner. They felt there was, therefore, no need for them to exert themselves in further physical work, what mattered was to watch and pray. When Paul received the news that some Thessalonians had folded their hands and refused to work and that they had even constituted themselves into a nuisance for the others, by either preventing them from their work or by solely depending on them for their bread, he had to write to them in very strong terms in order to disabuse the minds of such lazy people. Paul said categorically that whoever refuses to work should not eat. People should honestly help themselves to work, without eye-service, as if they were serving the Lord. He reminded them that when he was with them he was not parasitic, although he had the right to depend on them for his physical needs. He had worked with his own hands in order to maintain himself and be, for them, an exam worthy of emulation. It was therefore compulsory for the lazy to get down to work with their hands. But should they not heed his advice they should be boycotted to their shame. However, he warned that they should not be treated as enemies, but warned and re-directed with brotherly love, to retrace their steps and do the right thing.

Correct Answer: A. had learnt

Explanation

The sentence expresses a wish about something that did not happen in the past (when I was younger). When we express a wish or regret about a past event, we use the past perfect tense after I wish.

• I wish + past perfect = regret about the past.

Let's analyze the options:

• A. had learnt: This is the past perfect tense. Had learnt means had learned (both are acceptable past participles of learn). This fits the rule for expressing a wish about the past.

• B. learn: This is the base form/present simple. Incorrect.

• C. learnt: This is the past simple tense (or past participle). If it were I wish I *learnt* now, it would imply a present wish, but when I was younger refers to the past. Incorrect for a past regret.

• D. have learnt: This is the present perfect tense. Incorrect.

Therefore, the correct option is A.

The complete sentence is: I wish I had learnt to swim when I was younger.

The final answer is A

Correct Answer: D) liberation of heat

Explanation

Hydration of ions in solution is associated with theliberation of heat.

When an ionic compound dissolves in water, the ions in the compound are surrounded by water molecules. This process is called hydration. During hydration, the water molecules form a shell around the ions, stabilizing them in the solution. This process is exothermic, meaning it releases heat energy.

The reason for the liberation of heat during hydration is the strong electrostatic attraction between the charged ions and the polar water molecules. When this attraction leads to the formation of ion-dipole bonds, energy is released in the form of heat.

In summary, the hydration of ions in solution is associated with the liberation of heat because the formation of ion-dipole bonds between the ions and water molecules releases energy as heat.
