Benjamin Franklin, a prominent American scientist and statesman, invented both the lightning rod and bifocal spectacles. His lightning rod invention emerged from his experiments with electricity, including the famous kite experiment, which demonstrated that lightning is a form of electrical discharge.
The lightning rod protects buildings by directing electrical energy safely into the ground, preventing fires and structural damage. This invention had immediate practical importance and is still widely used today.
Franklin also invented bifocal spectacles to address his own vision problems. These glasses combine two lenses in one frame, allowing a person to see both near and distant objects clearly without switching glasses. This was a major convenience and innovation in optics.
Other options are notable scientists but unrelated to both inventions: Thomas Edison developed electric devices, Alessandro Volta invented the battery, and Benjamin Banneker was a mathematician and astronomer.
Therefore, Benjamin Franklin is the correct answer, as he contributed significantly to both electrical science and practical inventions improving daily life.

Paris climate conference held in?
A)
2012
B)
2015
C)
2016
D)
2017
The Paris Climate Conference, officially known as COP21, was held in 2015 in Paris, France. It brought together representatives from nearly every country to address the growing threat of climate change. The conference resulted in the historic Paris Agreement, a global pact aimed at limiting the rise in average global temperatures to well below 2°C above pre-industrial levels, with efforts to restrict it to 1.5°C.
This agreement is significant because it marked the first time that both developed and developing nations committed to reducing greenhouse gas emissions. Countries pledged to set nationally determined contributions (NDCs), which outline their climate action plans. The agreement also includes mechanisms for monitoring progress and providing financial support to developing nations.
The other options are incorrect because the Paris Agreement was specifically finalized in 2015. The year 2016 is associated with the agreement entering into force, not its negotiation.
Understanding the timeline of global environmental agreements is important in competitive exams and helps in building awareness of international cooperation. Therefore, 2015 is the correct answer as it represents a milestone in climate diplomacy and global environmental governance.

Batura glacier is located in?
A)
China
B)
Pakistan
C)
Afghanistan
D)
Tibet
The Batura Glacier is located in Gilgit-Baltistan, Pakistan, within the Karakoram mountain range. It is one of the longest glaciers outside the polar regions, stretching approximately 57 kilometers.
This glacier is significant because it contributes to the Hunza River, which is part of the Indus River system—Pakistan’s main water source. Glaciers like Batura are crucial for maintaining water supply for agriculture, hydropower, and daily use.
Unlike many glaciers worldwide that are retreating due to climate change, some glaciers in the Karakoram region, including Batura, have shown relative stability or even slight growth, a phenomenon known as the “Karakoram anomaly.”
Although the Karakoram range extends into China, the Batura Glacier lies within Pakistani territory. Afghanistan and Tibet do not contain this glacier.
Thus, Pakistan is the correct answer. Understanding glacier locations is important for geography, environmental science, and water resource management.

Kirthar mountain range is located in?
A)
Sindh
B)
Balochistan

Uch gas fields are located in?
A)
Balochistan
B)
Khyber Pakhtunkhwa
C)
Sindh
D)
Punjab
The Uch Gas Field is located in Balochistan, Pakistan, and is an important source of natural gas for the country. It was discovered in the mid-20th century and has been developed primarily to supply fuel for power generation.
Natural gas from Uch is used in thermal power plants, helping to generate electricity and support industrial activities. This contributes significantly to Pakistan’s energy sector and reduces reliance on imported fuels.
Balochistan is rich in natural resources, including gas, coal, and minerals. Other provinces like Sindh also have major gas fields, such as Qadirpur, but Uch specifically belongs to Balochistan.
Khyber Pakhtunkhwa and Punjab are not known for the Uch gas field. Therefore, Balochistan is the correct answer.
Knowledge of such resources is important for understanding national energy infrastructure and economic geography.

1st Governor General of State Bank of Pakistan?
A)
Zahid Hussain
B)
Shamshad Akhtar
C)
Abdur Rashid
D)
Malik Ghulam Muhammad
Zahid Hussain was the first Governor of the State Bank of Pakistan when it was established in 1948. The State Bank serves as the central bank of the country and is responsible for monetary policy, currency issuance, and financial stability.
As the first governor, Zahid Hussain played a crucial role in setting up the banking system of the newly independent Pakistan. His leadership helped establish financial institutions and regulatory frameworks.
Other options include later officials or unrelated figures. Shamshad Akhtar served much later, while Malik Ghulam Muhammad was a political figure.
Thus, Zahid Hussain is the correct answer, marking an important milestone in Pakistan’s economic history.
