Daily Current Affairs Prelims Quiz 30-10-2025 (Online Prelims Test)
1) Consider the following statements
An oval shaped eye of the cyclone indicates the very intense cyclone.
A high vertical shear of wind intensifies the cyclone, whereas the horizontal wind shear weakens it.
Select the correct statements using the code given below:
a.
b.
c.
d.
Answer : d
Explanation
Statement 1 is incorrect – An intense cyclone has clear round eye at the centre, when the cyclone gets weakened it starts to visible in oval shape at the eye of the center.
Statement 2 is incorrect – Vertical wind shear disrupts tropical cyclones by tilting their structure.
This weakens cyclones by moving the heat and moisture away from the core, separating the low-level circulation from the upper-level convection, and damaging their overall structure.
Horizontal wind shear can either weaken or strengthen a cyclone, depending on the circumstances.
It can shred a storm by displacing its core or help it intensify by moving it into warmer waters or by "venting" it in a way that allows it to strengthen.
The overall effect depends on the interaction between the storm's movement and the environmental winds.
2) Which of the following factors influences cyclone formation
Earth’s rotation
Ocean temperature
Low vertical wind shear
Choose the correct option using the code below:
a.
b.
c.
d.
Answer : c
Explanation
Earth’s rotation is the reason for the phenomenon of the Coriolis force and the Coriolis force is responsible for the rotation of the cyclonic wind. So 1 is correct.
The sea surface temperature is about 26º C or more, providing the heat and moisture for cyclones to grow.
The evaporated water in turn interact with the surrounding winds thus provided necessary speed for the cyclones. So 2 is correct.
A tropical cyclone is essentially a heat engine. It needs low vertical wind shear to keep its warm core aligned directly above its surface circulation center, which is crucial for intensification. So 3 is correct.
3) Consider the following

Answer : c
Explanation
Dayananda Saraswati was a prominent social reformer, philosopher, religious leader and founder of the Arya Samaj.

India’s 2nd President Sarvapalli Radhakrishnan called him as “a maker of modern India”.
5) “India’s Services Sector: Insights from Employment trends and State-Level Dynamics” report launched by?
a.
b.
c.
d.
Answer : a
Explanation
Recently, NITI Aayog has launched the report on “India’s Services Sector: Insights from Employment trends and State-Level Dynamics”.
The report is India’s 1st comprehensive study of employment in the services sector.
It analysis across sub-sectors, gender, regions, education levels, and job types—moving beyond aggregate trends to present a multi-dimensional workforce profile.
