Correct Answer: advanced

Solution : The third option is the correct answer.

The word cosmetically suggests that the blank should be filled with an adjective that describes the level of development or sophistication in the field of cosmetics. Advanced is an adjective that fits well in this context, indicating that South Korea is the most advanced country in terms of cosmetics.

Therefore, the right word to fill in the blank is advanced.

Correct Answer: PQSR

Solution : The correct choice is the fourth option.

The correct order of the sentence is PQSR.

This order ensures a logical flow of information, as it begins by introducing the challenge of pandemic-related travel complications (P), followed by the governance of key countries like India and France (Q), and their role in facilitating interactions between EDF and NPCIL (S). The sentence concludes by specifying the outcome of this interaction: EDF's ability to submit a binding techno-commercial offer on April 22, 2021 (R). This arrangement of the parts in a sentence maintains proper coherency and clarity.

Therefore, the complete sentence would be: Despite pandemic-related travel complications, the governments of India and France facilitated interactions between EDF and NPCIL, which allowed EDF to submit to NPCIL a binding techno-commercial offer on April 22, 2021.

Correct Answer: would have gone

Solution : The correct choice is the first option.

Explanation:
This is the case of the third conditional, which is used to talk about hypothetical situations and their potential outcomes, and the structure for this type of conditional is "would have + past participle" to indicate a hypothetical situation in the past and its hypothetical result. Thus, had gone should be replaced with would have gone to align with the structure of the third conditional.

Therefore, the correct sentence would be: If you had learned French, you would have gone to France for studies.

Correct Answer: Portugal and England

Solution : Given:
(I) In the European Championship Games, the flags of six countries were arranged on top of pillars in the following way. The flag of Argentina was to the left of Portugal's bi-colour and the right of the flag of France.

(II) The flag of England was to the right of the Portugal flag but to the left of the flag of Germany, which was to the left of the flag of Spain.

So, the flags of Portugal and England are in the middle of the row. Hence, the fourth option is correct. 

Correct Answer: RPQS

Solution : The correct choice is the fourth option.

The context helps identify that the paragraph is about the German invasion of the countries and northern France. Thus, to state the information provided chronologically, we follow the below steps:

• The paragraph starts with sentence R, which states that on May 10, 1940, the attack by Germans began with the capture by parachutists of key bridges that were deep in the country so that they could open a way for mobile ground forces.
• It is followed by sentence P, which tells the reaction of the Dutch defenders who fell back westwards, and by noon on May 12, German tanks were on the outskirts of Rotterdam.
• It is followed by sentence Q, which gives further information that the then-queen Wilhelmina and her government left the country on May 13, followed by the surrender of the Dutch army on May 13.
• The concluding statement of the paragraph is sentence S, which provides additional information on the invasion of Belgium, which also began on May 10.

Correct Answer: Paris

Solution : The correct option is Paris.

The Treaty of Paris, signed in 1763, concluded the hostilities of the Seven Years' War (also known as the French and Indian War) and resulted in the restoration of French possessions in India to France. The British forces, led by Sir Eyre Coote, defeated the French under the command of Comte de Lally at Wandiwash in southern India. This victory played a pivotal role in establishing British dominance in India.

Correct Answer: Spend

Solution : The first option is the correct choice.

The sentence is comparing the amount of money spent by citizens of South Korea on skincare products to consumers in the United States, the UK, and France. In this context, the verb that appropriately fits is spend, indicating the expenditure or amount of money used for purchasing skincare products.

Therefore, the right word to fill in the blank is spend.

Correct Answer: USA and Canada

Solution : The correct answer is USA and Canada.

The boundary between the two nations is marked for the majority of its length by the 49th parallel, a line of latitude that extends from the Strait of Georgia to Lake of the Woods. Both the Oregon Treaty of 1846 and the Anglo-American Convention of 1818 recognised the 49th parallel as the boundary. It has one of the world's longest undefended boundaries.

Correct Answer: perhaps

Solution : The first option is the correct choice.

In this case, perhaps is used to express a degree of uncertainty or likelihood. While it might not strictly adhere to a grammatical requirement, it fits the context of the sentence by suggesting that Korean shoppers may be among the world's most discerning, which allows for some uncertainty.

Therefore, the correct answer is perhaps.

Correct Answer: DACB

Solution : The correct choice is the first option.

The logical flow of sentences is as follows:

• The sequence begins with the decision to leave the small town after finishing school (D), setting the stage for the central characters.
• Subsequently, they decided to run away from home and managed to reach France on a cargo ship (A and C), showing the bold move they took to seek a better life.
• Upon reaching Paris, they mutually agreed to separate, as they desired independence (B), highlighting the individual paths they chose in pursuit of their goals.

Therefore, the correct order is DACB.
