The salinity of seawater is commonly expressed as the amount of dissolved salts in grams per kilogram of seawater. On average, seawater contains about 35 grams of dissolved salts per kilogram, not 1 gram. Sodium chloride (common salt) makes up about 85% of these dissolved salts, so roughly 30 grams of sodium chloride are present per kilogram of seawater. Therefore, the correct amount of common salt in 1 kilogram of seawater is approximately 30 grams, which is not among the options A (1 gram), B (10 grams), or C (1 kg). Hence, the correct answer is D (None of these).

Myanmar is not a member of SAARC. The member countries are Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka. Therefore, Myanmar is correctly identified as not a member.

The displacement vector from P(1,1,1) to Q(1,2,2) is (0,1,1). The work done is the dot product of force F = (1,1,1) and displacement vector (0,1,1), which equals 1*0 + 1*1 + 1*1 = 2.

The word 'divulge' means to reveal or disclose information, which fits the context of not revealing further information to avoid jeopardizing the investigation. The other options do not fit as precisely in this context.

Option A correctly uses 'cause and effect' to describe the relationship that remains the focus of scientific investigation, with proper singular agreement. Option B incorrectly uses 'affect' instead of 'effect'. Option C incorrectly pluralizes 'relationships' which changes the meaning. Option D is incorrect as option A is correct.

Jupiter is commonly known as the 'Bodyguard of the Earth' because its massive gravitational field acts as a cosmic shield, deflecting, capturing, or ejecting many comets and asteroids that might otherwise collide with Earth. While Saturn also has a strong gravitational influence, Jupiter's role in protecting Earth from many potential impacts is more significant and widely recognized in astronomy.

Antonio Guterres has been the Secretary-General of the United Nations since January 1, 2017, succeeding Ban Ki-moon. Therefore, option A is correct.

Rajab is the seventh month in the Islamic (Hijri) calendar. The options correctly list '7th' as option C, so the correct answer is 'C'. The original correct_answer was incorrectly set to 'A' (6th), but the factual month number for Rajab is 7th.

The Great Spot, commonly known as the Great Red Spot, is a giant storm on the planet Jupiter. It is a persistent high-pressure region in Jupiter's atmosphere, producing an anticyclonic storm.

The five planets visible to the naked eye without a telescope are Mercury, Venus, Mars, Jupiter, and Saturn. These planets have been known since ancient times and can be seen as steady points of light that do not twinkle. Uranus is barely visible to the naked eye under very dark skies and excellent eyesight, but it is generally considered not visible without optical aid. Neptune and Pluto are too faint to be seen without a telescope. Therefore, the correct answer is 5, which corresponds to option D.
