Historians have discovered that a type of natural glass – obsidian – ……”. The synonym of sharp points is also found in line 7, ‘……. – was first used as tips of spears.”
1. obsidian, 2. spears
Question 3: 4000 BC: 3 ______ made of stone were covered in a coating of man-made glass.

Now, in paragraph A, lines 8-11 says, “Archaeologists have even found evidence of man-made glass which dates back to 4000 BC; this took the form of glazes used for coating stone beads.”
Here, we can see the direct references from the questions to the keywords like man-made glass, 4000 BC, coating and stone. So, the
thing that was made of stone was beads.
Question 4: First century BC: glass was coloured because of the 4 _____ in the material.
Keywords: First century BC, was coloured, because
Now, in paragraph B, lines 3-5 says, “….. from the first century BC . The glass made during this time was highly coloured due to the impurities of the raw material.”

First century BC, highly coloured = coloured; and due to = because;
Question 5: Until 476 AD: Only the 5 ______ knew how to make glass.
Keywords: Until 476 AD, Only, knew how to make glass
Now, in paragraph 2, lines 9-17 say, “The secret of glass making was taken across Europe by the Romans during this century. However, they guarded the skills and technology required to make glass very closely, and it was not until their empire collapsed in 476 AD that glassmaking knowledge became widespread throughout Europe and the Middle East.”
These lines suggest that only the Romans knew about how to make glass until the collapse of their empire in 476 AD.
Question 6 and 7: 17 century: George Ravenscroft developed a process using 6 ______ to avoid the occurrence of 7 ______ in blown glass.
Keywords: 17th century, George Ravenscroft, developed a process, using, to avoid, in blown glass

occurred in blown glass by introducing lead to the raw materials used in the process.”.
Here, counter = to avoid
So, it can be understood here that George Ravenscroft developed a process by using lead so that the occurrence of clouding can be avoided.
Answers are: 6. lead, and 7. clouding

Here, we can gather from the text that British glass production was in a problem in the mid-19th century (1745-1845) when there were taxes for glass blowing industry. But after the Excise Act was repealed in 1845, the industry only started to develop.

Question 9: In 1887, HM Ashley had the fastest bottle-producing machine that existed at the time.
Keywords: 1887, HM Ashley, fastest, bottle-producing, existed at the time
Now, to find the answer for this question, find the given year (1887). If you just brush your eyes on each paragraph quickly, you will find the year in Paragraph 5. Now, read the first few lines and try to find the other keywords.
In line 4, we can find HM Ashley, the name of the glass factory. In lines 7 and 8, the writer mentions, “…. – more than three times quicker than any previous production method.” This means HM Ashley was the fastest bottle-producing machine of that time.
Question 10: Michael Owens was hired by a large US company to design a fully-automated bottle manufacturing machine for them.
Keywords: Michael Owens, was hired, by large US company, to design, fully-automated, machine
Now, the answer can be found in lines 8-10. Here, it is mentioned that Michael Owens owned a large US company, he was not hired by them. Check the lines, “……Michael Owens – founder of the Owens Bottle Machine Company (later the major manufacturers Owens-Illinois).”
Here, founder = owner;

most glass production is done by large international manufacturers or not.
Answer: NOT GIVEN

Keywords: Concern, environment, leading to, increased demand
Now, in paragraph 7, the first few lines contain the answer. Here the lines say, “…… and with growing consumer concern for green issues, glass bottles and jars are becoming even more popular.” It means that the consumers of glass are worried about the environmental issues (green issues) and this is making the production of glass even more popular (increased demand).
Question 13: It is more expensive to produce recycled glass than to manufacture new glass.
Keywords: more expensive, produce recycled glass, than, manufactured new glass
Now, in paragraph 7, lines 6-10 say, “….. As less energy is needed to melt recycled glass than to melt down raw materials, this also saves fuel and production costs.” So, it is clear that producing glass actually saves money which means it is less expensive.
