Saudi Arabia shuts its East-West oil pipeline after attacks: why it matters for India
Saudi Arabia's East-West Crude Oil Pipeline, shut after attacks in September 2026, carries crude from:
- Ras Tanura on the Persian Gulf to Jeddah on the Red Sea
- Abqaiq in the Eastern Province to Yanbu on the Red Sea
- Abqaiq to Fujairah on the Gulf of Oman
- Yanbu to the Suez Canal
Show answer
Answer: (b) Abqaiq in the Eastern Province to Yanbu on the Red Sea. The pipeline runs about 1,200 km from the Abqaiq field in the Eastern Province to Yanbu on the Red Sea, so that exports can avoid the Strait of Hormuz. Fujairah is in the UAE and is served by a different (UAE) pipeline.
Consider the following statements about Saudi Arabia's East-West Crude Oil Pipeline:
1. It ends at Yanbu on the Red Sea.
2. It was built after the 2019 drone attacks to bypass the Strait of Hormuz.
3. It is owned and operated by Saudi Aramco.
How many of the statements given above are correct?- Only one
- Only two
- All three
- None
Show answer
Answer: (b) Only two. Statement 1 is correct. Statement 2 is incorrect: it was built in the 1980s during the Iran-Iraq War and commissioned in 1981; 2019 was when Houthi drones attacked it. Statement 3 is correct.
Consider the following pairs:
1. Strait of Hormuz : Persian Gulf and Gulf of Oman
2. Bab el-Mandeb : Red Sea and Gulf of Aden
3. Strait of Malacca : Andaman Sea and South China Sea
4. Strait of Hormuz : Red Sea and Mediterranean Sea
How many of the pairs given above are correctly matched?- Only one
- Only two
- Only three
- All four
Show answer
Answer: (c) Only three. Pairs 1, 2 and 3 are correct. Pair 4 is wrong: the Red Sea connects to the Mediterranean through the Suez Canal, not the Strait of Hormuz.
Consider the following statements:
Statement-I: The shutdown of the East-West pipeline raises the risk to Saudi oil exports from threats in the Strait of Hormuz.
Statement-II: The pipeline lets Saudi crude reach the Red Sea without passing through the Strait of Hormuz.
Which one of the following is correct in respect of the above statements?- Both Statement-I and Statement-II are correct and Statement-II explains Statement-I
- Both Statement-I and Statement-II are correct and Statement-II does not explain Statement-I
- Statement-I is correct but Statement-II is incorrect
- Statement-I is incorrect but Statement-II is correct
Show answer
Answer: (a) Both Statement-I and Statement-II are correct and Statement-II explains Statement-I. Both are correct and linked: because the pipeline is the bypass around Hormuz, closing it pushes more Saudi exports back towards the Gulf route.
With reference to India's current account, consider the following statements:
1. Remittances from Indians working abroad are recorded in the current account.
2. A rise in crude oil prices tends to widen India's current account deficit.
Which of the statements given above is/are correct?- 1 only
- 2 only
- Both 1 and 2
- Neither 1 nor 2
Show answer
Answer: (c) Both 1 and 2. Both are correct. Remittances are secondary income in the current account, and crude is India's largest import, so higher prices raise the deficit.

Study finds rapid Himalayan erosion releases CO2 through pyrite oxidation
Consider the following processes:
1. Weathering of silicate rocks by carbonic acid in rainwater
2. Dissolution of carbonate rocks by sulphuric acid formed from pyrite oxidation
3. Burial of organic carbon in ocean sediments
Which of the above tend to release carbon dioxide to the atmosphere over geological time?- 1 only
- 2 only
- 1 and 3 only
- 2 and 3 only
Show answer
Answer: (b) 2 only. Only 2 releases CO2: sulphuric acid dissolving carbonate frees carbon that was locked in rock. Silicate weathering (1) and burial of organic carbon (3) remove CO2 from the atmosphere over long timescales.
Consider the following statements about the upper Indus basin study reported in September 2026:
1. It found that steep, fast-eroding mountain stretches act as net sources of CO2.
2. It found that downstream floodplains act as carbon sinks.
3. It used sulphur and oxygen isotope ratios to trace the source of river sulphate.
How many of the statements given above are correct?- Only one
- Only two
- All three
- None
Show answer
Answer: (c) All three. All three are correct as reported: steep mountains are net sources, floodplains are sinks, and isotope ratios of sulphur and oxygen in sulphate were used to identify pyrite as a source.
Consider the following statements:
1. Carbonic acid in rainwater forms when CO2 dissolves in water.
2. Silicate weathering by carbonic acid removes CO2 from the atmosphere over long timescales.
3. Pyrite is a carbonate mineral.
4. Glaciers can speed up chemical weathering by exposing fresh rock surfaces.
How many of the statements given above are correct?- Only one
- Only two
- Only three
- All four
Show answer
Answer: (c) Only three. Statements 1, 2 and 4 are correct. Statement 3 is incorrect: pyrite is an iron sulphide, not a carbonate.
Consider the following statements:
Statement-I: In rapidly eroding parts of the upper Indus basin, rock weathering was found to be a net source of CO2.
Statement-II: Sulphuric acid formed by pyrite oxidation dissolves carbonate rocks and releases CO2, and this release exceeded the CO2 taken up by silicate weathering.
Which one of the following is correct in respect of the above statements?- Both Statement-I and Statement-II are correct and Statement-II explains Statement-I
- Both Statement-I and Statement-II are correct and Statement-II does not explain Statement-I
- Statement-I is correct but Statement-II is incorrect
- Statement-I is incorrect but Statement-II is correct
Show answer
Answer: (a) Both Statement-I and Statement-II are correct and Statement-II explains Statement-I. Both are correct, and Statement-II gives the mechanism: the pyrite-sulphuric acid route released about three times the CO2 that silicate weathering removed, so the net effect was a source.
With reference to the carbonate-silicate cycle, consider the following statements:
1. It regulates Earth's climate over millions of years.
2. Higher temperatures slow down silicate weathering.
Which of the statements given above is/are correct?- 1 only
- 2 only
- Both 1 and 2
- Neither 1 nor 2
Show answer
Answer: (a) 1 only. Statement 1 is correct. Statement 2 is incorrect: higher temperatures and more rain speed up silicate weathering, which is why the cycle acts as a negative feedback.
Spreading finely ground basalt on farmland is discussed as a method of:
- Reducing soil salinity by leaching
- Carbon dioxide removal through enhanced weathering
- Increasing soil acidity for tea cultivation
- Preventing wind erosion in deserts
Show answer
Answer: (b) Carbon dioxide removal through enhanced weathering. This is enhanced rock weathering: crushed basalt weathers quickly and locks CO2 into bicarbonate. UPSC's 2023 Prelims listed it among carbon capture methods.
First Badri calf born through OPU-IVF, a boost for Uttarakhand's hill cattle
With reference to the Ovum Pick-Up and In Vitro Fertilisation (OPU-IVF) technique used to produce a Badri calf in 2026, which one of the following statements is correct?
- The eggs are collected only after the donor cow is slaughtered.
- Eggs are collected from a live donor cow using an ultrasound-guided needle and fertilised in the laboratory before the embryo is transferred to a recipient cow.
- The calf is a genetic copy of the recipient cow that carries it.
- The technique involves inserting a gene from another species into the embryo.
Show answer
Answer: (b) Eggs are collected from a live donor cow using an ultrasound-guided needle and fertilised in the laboratory before the embryo is transferred to a recipient cow.. OPU collects eggs from a live donor with ultrasound guidance; IVF fertilises them in the lab; embryos go into recipient cows. The calf inherits the genes of the egg donor and the bull, not the recipient, and no foreign gene is inserted.
Consider the following statements about the Badri calf born in September 2026:
1. It was produced through ovum pick-up and in vitro fertilisation.
2. It was carried to term by a Badri cow.
3. It is a clone of an elite Badri cow.
How many of the statements given above are correct?- Only one
- Only two
- All three
- None
Show answer
Answer: (a) Only one. Only statement 1 is correct. Statement 2 is wrong: a Sahiwal cow was the recipient. Statement 3 is wrong: the calf came from IVF with Badri bull semen; cloned Badri embryos are a separate, later step.
Consider the following statements:
1. In ovum pick-up, eggs are collected from a live donor cow.
2. In embryo transfer, the calf inherits the genes of the recipient cow.
3. OPU-IVF can multiply the genes of elite female animals faster than natural breeding.
4. Artificial insemination alone spreads the genes of elite bulls, not of elite cows.
How many of the statements given above are correct?- Only one
- Only two
- Only three
- All four
Show answer
Answer: (c) Only three. Statements 1, 3 and 4 are correct. Statement 2 is wrong: the recipient only carries the pregnancy; the calf's genes come from the egg donor and the bull.
Consider the following statements:
Statement-I: A Sahiwal cow can give birth to a pure Badri calf.
Statement-II: In embryo transfer, the recipient cow provides only the womb, and the calf's genes come from the egg donor and the bull.
Which one of the following is correct in respect of the above statements?- Both Statement-I and Statement-II are correct and Statement-II explains Statement-I
- Both Statement-I and Statement-II are correct and Statement-II does not explain Statement-I
- Statement-I is correct but Statement-II is incorrect
- Statement-I is incorrect but Statement-II is correct
Show answer
Answer: (a) Both Statement-I and Statement-II are correct and Statement-II explains Statement-I. Both are correct and linked: because the recipient contributes no genes, a Sahiwal cow can carry a Badri embryo to term, as happened at Pantnagar.
With reference to A1 and A2 milk, consider the following statements:
1. A1 and A2 are variants of the milk protein beta-casein.
2. Indian indigenous cattle such as the Badri typically produce milk with the A2 form.
