The correct answer is (b) Our Nurses. Our Future. Caring for nurses strengthens economies

• The theme for International Nurses Day 2025 is "Our Nurses. Our Future. Caring for nurses strengthens economies".

• This theme highlights the importance of nurse well-being, advocating for greater investment in their welfare and recognizing the significant economic impact that a healthy and supported nursing workforce can have.

• The focus is on the urgent need to prioritize nurse wellness, tackle nurse shortages, and provide better working conditions to ensure resilient healthcare systems globally.

• The theme calls for structural reforms in nursing education, staffing, and leadership development, which are essential for sustainable healthcare and robust economies.

Information Booster:

• Florence Nightingale, the founder of modern nursing, was born on May 12, which is why this day is observed annually.

• The International Council of Nurses (ICN), which organizes the observance, advocates for increased funding, fair wages, safer working environments, and mental health support for nurses.

• Nurse burnout and stress are significant issues faced globally, which this day aims to raise awareness about.

• The Lamp Lighting Ceremony, a symbol of Nightingale’s legacy, is a central part of the celebrations.

• The theme emphasizes the interdependence between the well-being of nurses and the economic resilience of nations.

• Over the years, the focus has evolved from celebrating nurses to advocating for their rights, welfare, and recognition as key contributors to economic stability.

Given:

√45 +√125 = 17.89

Solution:

√45 +√125 = 17.89

=> 3√5 + 5√5 = 17.89

=> 8√5 = 17.89

Now solve

√180 +√80

=> 6√5 + 4√5 = 10√5

=> 10√5 = 17.89 × (10√5/8√5)

=> 10√5 = 17.89 × (5/4)

=> 10√5 = 22.4

The correct answer is (C) Spinach

Explanation:

Oxalic acid is naturally found in spinach and several other vegetables. It is an organic compound that can form insoluble salts when combined with calcium, often referred to as calcium oxalate. While oxalic acid is present in many plants, spinach is particularly known for having a significant amount.

Information Booster:

• Oxalic acid in spinach can affect the absorption of minerals like calcium and iron.

• It is found in other foods like rhubarb, beets, and kale as well.

• Oxalic acid can contribute to kidney stone formation in sensitive individuals when consumed in large quantities.

• Cooking spinach can reduce its oxalic acid content.

• It is a naturally occurring substance, not artificially added to food.

Additional Information:

• Lemon: While lemon is acidic, it does not contain oxalic acid. Its main acid is citric acid.

• Vinegar: Vinegar contains acetic acid, not oxalic acid.

• Milk: Milk is rich in calcium but does not contain oxalic acid.

Correct Answer is: BCAYKRAD

Given: In a certain code, SYLLABUS is written as SLYALUBS.

Logic: Position of the letters are interchanged.

So, BACKYARD is written as BCAYKRAD.

Thus, correct option is (d).

The Correct Answer is: (d) Arthropoda

Explanation:

Arthropoda is the largest phylum in the animal kingdom, comprising more than 80% of all known animal species. This phylum includes insects, arachnids (spiders, scorpions), crustaceans (crabs, lobsters), centipedes, and millipedes. Arthropods are characterized by a segmented body, jointed appendages, and a chitinous exoskeleton. Their adaptability, complex behaviors, and reproductive strategies have enabled them to inhabit a wide range of environments – from deep oceans to mountaintops and even deserts.

Information Booster:

• Phylum Arthropoda includes more than 10 lakh (1 million+) known species.

• Insects alone (class Insecta) make up the majority of arthropods.

• Arthropods have an open circulatory system and a ventral nervous system.

• Their body is divided into three main parts: head, thorax, and abdomen (especially in insects).

• Exoskeleton made of chitin provides protection and prevents water loss.

• They undergo molting (ecdysis) to grow, shedding the old exoskeleton.

• Economic importance: Some are pests (e.g., locusts), vectors (e.g., mosquitoes), while others are useful (e.g., honeybees, silkworms).

Additional Information:

• Chordata – Includes animals with a notochord, such as mammals, birds, reptiles, amphibians, and fish. It is not the largest phylum.

• Annelida – Segmented worms like earthworms and leeches. They are fewer in number compared to arthropods.

• Mollusca – Second-largest phylum; includes snails, octopuses, squids, etc. Soft-bodied animals, often with a calcium carbonate shell.

​The correct answer is (b) - Depends on the shape of the conductor

Explanation:

• The pattern of magnetic field lines around a current-carrying conductor depends on its shape.
• According to Ampère’s Circuital Law and the Right-Hand Thumb Rule, the magnetic field forms different patterns around different conductor shapes.
• For example:
  • Straight Conductor: Field lines form concentric circles around the wire.
  • Circular Loop: Field lines form concentric circles near the wire and straighten at the center.
  • Solenoid: Field lines resemble that of a bar magnet, with north and south poles.

Information Booster:

Magnetic Field Patterns for Different Conductors:

• Straight Conductor: Field lines are circular and centered around the wire.
• Circular Loop: Field lines converge at the center, forming a strong magnetic field.
• Solenoid (Coil of Wire): Produces a magnetic field similar to a bar magnet, with well-defined poles.
  Toroid (Circular Coil Bent into a Ring): Field lines remain confined inside the ring.

Given:

Six students (U, V, W, X, Y, and Z) are sitting around a circular table, facing the center.

X is the immediate neighbor of W.​

V is seated third to the left of W.

U is seated to the immediate right of Y.

V is seated second to the right of X.

According to the given information, Circular seating arrangements will be:

As per the seating arrangements, U is seated third to the left of Z.

Thus, the Correct option is (d) U

Given:

The radius of the base of a conical tent is 9 m and its height is 12 m

Formula Used:

Curved surface area of a cone = π × Radius × Slant Height

Correct Answer is: 2027
