Icelandic, a North Germanic language, is the national and official language of Iceland. It is known for having changed little since the time of the settlement of the island.

The common cold is a viral infectious disease of the upper respiratory tract. The most frequent causative agents are rhinoviruses, although other viruses such as coronaviruses, adenoviruses, and respiratory syncytial viruses can also be responsible. Because it is viral, it cannot be cured by antibiotics.

In Microsoft PowerPoint, the keyboard shortcut Ctrl + K is the standard command used to open the 'Insert Hyperlink' dialog box. This allows users to link text or objects to external websites, other files, or specific locations within the presentation.

The Indus Waters Treaty, brokered by the World Bank in 1960, divided the rivers of the Indus Basin between India and Pakistan. India was given exclusive rights to the waters of the three eastern rivers: the Ravi, the Sutlej, and the Beas, while Pakistan received rights to the western rivers.

**AP** is a program in the United States and Canada created by the College Board which offers college-level curricula and examinations to high school students.

In this reaction, the hydroxy group of phenol increases its reactivity towards electrophilic attack, allowing it to form a stable compound with bromine, resulting in a creamy white precipitate.

A hypothesis is a tentative statement about the relationship between two or more variables. It serves as a guide for the researcher by specifying what data needs to be collected and analyzed to test the validity of the proposed relationship. By directing the focus toward specific variables, the hypothesis helps structure the empirical investigation and the interpretation of the resulting data.

Sieve elements are specialized conducting cells found in the phloem of vascular plants. They are characterized by the presence of sieve areas, which are clusters of pores that facilitate the transport of organic nutrients.

Feminist literary theory seeks to dismantle patriarchal structures within literature. Its objectives include recovering neglected female authors, analyzing the representation of women as literary subjects, critiquing phallocentric (male-centered) biases in critical traditions, and challenging the pervasive stereotypes that have historically limited female characters. By doing so, it aims to foster a more equitable and inclusive understanding of gender dynamics in both literary production and critical reception.

The Treaty of Yandabo ended the First Anglo-Burmese War, with Burma ceding Assam, Manipur, Arakan, and Tenasserim to the British.

The IMF uses Special Drawing Rights (SDRs) as its unit of account. Member country quotas, which determine their financial contribution and voting power within the organization, are denominated in SDRs, which represent a basket of major international currencies.

Shock absorbers function by dissipating kinetic energy to dampen vibrations. Steel is chosen for its high elasticity (specifically, its ability to return to its original shape after deformation) and its high tensile strength. This allows the component to undergo repeated stress cycles without permanent deformation, effectively absorbing and releasing energy during mechanical impacts.

Ethnocentrism is the sociological concept where an individual evaluates other cultures based on the standards and values of their own culture. This often leads to the belief that one's own group is superior, serving as a lens through which the world is interpreted and judged.

**Rule: While names of games don't take an article, the noun 'game' does.** We say 'play badminton' (no article), but when we refer to a single instance of playing, we say 'a game of badminton'. 'Game' is a singular countable noun starting with a consonant sound, so 'a' is correct. Option (b) is wrong by sound. Option (c) would refer to a specific, planned game. Option (d) is incorrect.

OSI stands for Open Systems Interconnection. It is a conceptual framework developed by the International Organization for Standardization (ISO) to standardize the functions of a telecommunication or computing system into seven distinct layers.

Kinetic energy is calculated using the formula KE = 0.5 * m * v^2. Substituting the given values: KE = 0.5 * 10 kg * (5 m/s)^2 = 5 * 25 = 125 Joules. This formula accounts for the mass and the square of the velocity.

In biochemistry, an enzyme functions by binding to a specific molecule known as the substrate. This binding occurs at the enzyme's active site, forming an enzyme-substrate complex. The enzyme then facilitates the chemical transformation of the substrate into the final product, lowering the activation energy required for the reaction.

The first Arab-Israeli War, which broke out in 1948 following the end of the British Mandate and the declaration of the State of Israel, concluded in 1949. The conflict ended with a series of armistice agreements signed between Israel and its neighboring Arab states—Egypt, Lebanon, Jordan, and Syria—which established the 'Green Line' as the de facto border.
