The correct matching is A-4, B-2, C-1, D-3. Iron oxide is often used as a preparatory coating or primer on steel to prevent rust. Varnish is a clear, colourless coating that provides a protective and shining finish, typically on wood. Enamel paint dries to a hard, durable, often glossy finish and is used on surfaces like wood and metal. Emulsion paint is a water-based paint commonly used on interior and exterior walls, including brick walls.

– Iron oxide primers (like red oxide) are widely used for corrosion protection on steel.
– Varnish provides a clear, protective layer, enhancing the natural look of wood.
– Enamel paints are known for their hard, glossy finish and durability on various surfaces.
– Emulsion paints are standard for architectural use on walls.

Different types of paints and coatings are formulated for specific purposes, surfaces, and desired finishes. Primers (like iron oxide based) prepare the surface for the topcoat and improve adhesion and durability. Varnishes are transparent finishes. Enamels provide opaque, durable finishes. Emulsions are typically water-based and dry relatively quickly, making them popular for internal walls.

Let’s examine the characteristics of each local wind:
A) Sirocco: A hot, dry wind originating in the Sahara Desert and blowing northward across the Mediterranean Sea. It picks up moisture over the sea but is initially hot and dry.
B) Mistral: A strong, cold, dry wind that blows from the north down the Rhône Valley in France towards the Mediterranean Sea. It is associated with high pressure and clear, cold weather.
C) Khamsin: A hot, dry, sandy wind blowing from the south over Egypt and the Middle East, typically occurring in spring. Similar in nature to Sirocco.
D) Chinook: A type of Foehn wind that occurs on the eastern side of the Rocky Mountains in North America. It is a warm, dry wind caused by air descending the leeward side of a mountain range.
Comparing these, Sirocco, Khamsin, and Chinook are all characteristically hot and dry. Mistral is characteristically cold and dry.

Local winds have distinct characteristics regarding temperature, moisture content, and origin. Identifying a wind that is *not* hot and dry among a list of predominantly hot and dry winds requires knowing the specific nature of each wind type.

Foehn winds like the Chinook are warm because the descending air is compressed and warms adiabatically after losing moisture on the windward side of the mountain. The Mistral, conversely, is a katabatic wind, associated with cold air flowing down from elevated, cold landmasses or plateaus, channeled through valleys.

Let’s determine the relative locations of these hill ranges in southern India:
3. Nallamala Hills are part of the Eastern Ghats and are located in Andhra Pradesh and Telangana, making them the northernmost range among the options.
1. Nilgiri Hills are located at the junction of the Eastern and Western Ghats, in Tamil Nadu, Kerala, and Karnataka, south of the Nallamalas.
4. Anaimalai Hills are part of the Western Ghats, located south of the Nilgiris in Tamil Nadu and Kerala. They contain Anai Mudi, the highest peak in South India.
2. Cardamom Hills are the southernmost extension of the Western Ghats, located south of the Anaimalai hills in Tamil Nadu and Kerala.
Arranging them from north to south gives the order: Nallamala, Nilgiri, Anaimalai, Cardamom (3-1-4-2).

The correct arrangement requires knowledge of the geographical location of prominent hill ranges in South India relative to each other along a north-south axis. Nallamala is in the Eastern Ghats further north, while Nilgiri, Anaimalai, and Cardamom are sequential ranges in the Western Ghats moving southwards.

The Western Ghats and Eastern Ghats converge at the Nilgiri Hills. The Anaimalai Hills are known for their rich biodiversity and include several protected areas. The Cardamom Hills are famous for the cultivation of cardamom, pepper, and coffee.

India currently uses a single time zone based on 82.5° E longitude (IST). States located further east experience sunrise and sunset significantly earlier than the clock time suggests, leading to practical issues like late starts to the day according to solar time. Adopting a second time zone based on 90° E would align clock time better with solar time for eastern states. The benefit would be most pronounced for states located furthest to the east, as the difference between their solar time and the current IST is largest. Among the given options of eastern Indian states, Manipur is geographically located furthest to the east. Therefore, it would experience the greatest positive impact from a separate eastern time zone based on 90° E.

The need for separate time zones in India is primarily felt in the extreme eastern states due to the large longitudinal extent of the country, causing a significant difference between local solar time and the standard time based on 82.5° E.

The difference in solar time between the easternmost and westernmost points of India is approximately two hours. States like Arunachal Pradesh in the extreme east see sunrise as early as 4 AM IST in summer. A separate time zone for the northeast region, based on a more easterly meridian like 90° E or 97.5° E, has been proposed multiple times to address this issue, which impacts productivity and energy consumption.

The Border Security Force (BSF) is primarily responsible for guarding India’s land border with Pakistan and Bangladesh. The Sashastra Seema Bal (SSB) guards the borders with Nepal and Bhutan. The Indo-Tibetan Border Police (ITBP) guards the border with China (along with the Army in certain sectors). The Assam Rifles is responsible for guarding the border with Myanmar. Therefore, the correct match is A-2, B-3, C-1, D-4. This corresponds to option A in the given codes.

Different Central Armed Police Forces (CAPFs) and other forces are assigned specific international borders of India for security and management.

Other forces involved in border guarding or internal security in border areas include the Army, Coast Guard, and state police forces, depending on the specific threat perception and terrain. The ITBP is deployed along the mountainous Indo-China border. The SSB replaced the Special Service Bureau (SSB) for guarding the open borders with Nepal and Bhutan. The Assam Rifles is the oldest paramilitary force in India and primarily operates in the Northeast, guarding the Myanmar border.

Based on the data related to language speakers (which is not provided here), the total number of boys who speak English and the total number of girls who speak English are in the ratio 5:8.

This ratio is obtained by dividing the total number of boys speaking English (English only + both) by the total number of girls speaking English (English only + both), as given in the original data set, and simplifying the resulting fraction.

To solve this, one would calculate the total number of boys speaking English and the total number of girls speaking English from the provided data and then determine their ratio. The specific ratio ‘5:8’ results from the particular totals in the original data source for the question.
