The main text of “The Story of Platinum” is given below. Students are advised to read the essay carefully and then move on to the questions.
The Story of Platinum
A. The White metal Platinum is much denser and rarer than gold, in fact, some 30 times rarer. To acquire an ounce of platinum, it takes about ten tonnes of ore. Similar to gold, it is supposed to have come to earth in meteorites, the earliest recorded having hit the planet off the coast of western Greenland about three billion years ago.
B. The earliest recorded evidence of platinum use is in gold jewellery from Nubia with traces of platinum in 1200 BC and famously on a box from an Egyptian tomb in Thebes dating from 700 BC. Platinum also made appearances in pre-Columbian artefacts in South America, where platinum was used for decorative purposes to adorn the body including earrings and masks with the earliest known piece being that of a small platinum head. Evidence of platinum use did not appear again in South America until the time of the Incas, the most famous of the civilizations of South America. It was not until the time of the Spanish Conquistadors' arrival in South America in the 15th and 16th centuries that the first Europeans came into contact with platinum. It was, however, considered by the new arrivals as an inferior form of silver, from which it took its name platina, meaning small silver in Spanish. Ignorant of the skills of the local people, they were unable to melt it, so platinum was thrown back into rivers.
C. When platinum was finally identified and classified as a new metal in the 18th century it began to attract the interest of scientists in Europe. Being very hard and having a high melting point, however, it took time for scientists to develop ways to melt the metal. A concave mirror device created in 1758 by Macquer, a French scientist, managed to melt platinum, but the method was cumbersome. In 1786, a French court jeweller, Janety, used arsenic to create an alloy of platinum that was then refined to make pure platinum. In Spain and England, other experiments were carried out, but in 1782 Antoine Lavoisier succeeded in melting platinum using a high-temperature torch made from oxygen and hydrogen. Once melting was made possible, its use in making jewellery was greatly enhanced.
D. Platinum, as the other precious metals gold and silver before it, became a store of value. In jewellery, platinum accounts for only 30% of the approximate eight tonnes of the metal mined each year. Unlike gold, platinum does not wear away; in fact, because of its durability, the International Prototype Kilogram - stored at Sèvres in France - is made of platinum. Apart from its intrinsic value as a rare metal, platinum is desirable in jewellery for various reasons. Due to its very hardness, it is hypoallergenic, i.e. it does not cause allergy, unlike other metals such as gold; it does not reflect colour onto diamonds, which it can secure tightly as a result of strength and hardness.
E. Platinum is well known for its industrial use. The bulk of Platinum is used in the car industry in areas such as catalytic converters as platinum is able to absorb a huge amount of hydrogen, which makes it useful for environmental cleanup. The current manufacturers of glass, as in the past, along with anti-cancer medication, fibre-optic cables and LCD displays are all reliant on platinum. It is also a key component of fuel cells, which is used to convert hydrogen and oxygen into energy with water being a waste product.
F. Being a rare metal, platinum is only found in a few locations around the world. Up until the early part of the 19th century Columbia was the only source of platinum. In 1820, various deposits were discovered in the Ural mountains of Russia, still a major source today. There are minor deposits in Montana, USA, but the main supplier of platinum today is South Africa where the world’s largest deposits were discovered in 1920s.
G. Russia minted 1.5 million coins, but ceased it during so when the value of metal exceeded that of coins. Today, various platinum coins, such as the Australian Koala and the Canadian Maple Leaf in 1988. The Chinese Panda in 1987 and the American Eagle in 1997, have been available in one ounce sizes or less, and bars of platinum weighing ten ounces and smaller sizes for investment.

What are the Answers of the Questions asked in The Story of Platinum Reading Answers Passage?
Here are the answers to the questions asked above with complete explanations.
1. B (They disregarded it as a nuisance)
Explanation: (Paragraph B) Spanish conquistadors were unable to melt platinum, ignorant of the skills of local people. Failing to do so, they disregarded it as a nuisance and threw it back into rivers.
2. C (Melting Platinum)
Explanation: (Paragraph C) Due to the high melting point of platinum, the European scientists faced difficulties in melting platinum. It took some time for scientists to develop methods to melt platinum and finally in 1782 Antoine Lavoisier succeeded in melting it.
3. A (Durability)
Explanation: (Paragraph D) It is mentioned in the essay “Unlike gold, platinum does not wear away; in fact, because of its durability, the International Prototype Kilogram - stored at Sèvres in France - is made of platinum.”.
4. C (Making Utensils)
Explanation: It is not mentioned anywhere in the passage. In fact, due to its rarity, it cannot be used in making utensils.

Explanation: (Paragraph G) Mentioned in the passage “Russia minted 1.5 million coins, but ceased it during so when the value of metal exceeded that of coins”.
6. TRUE
Explanation: Paragraph A states that the earliest recorded meteorite hit the Earth off the coast of western Greenland about three billion years ago, bringing elements like platinum. So, this statement is directly supported by the text.
7. NOT GIVEN
Explanation: Paragraph B mentions that the Incas used platinum but does not compare their knowledge with others. There's no information about whether they had more knowledge than other civilizations or groups, so the claim can't be verified.
8. FALSE
Explanation: Paragraph E says “current manufacturers of glass, as in the past” still rely on platinum. This means platinum is still being used in glass production today, contradicting the statement.
9. TRUE
Explanation: Paragraph F clearly states that South Africa is the main supplier of platinum today, after large deposits were discovered there in the 1920s. So, this statement aligns with the passage.
