Paragraph 4
As oil becomes increased different to find, the search for it is extended into more- hostile environments.
The development of the oil on the North Slpoe of Alaska and construction of the Alaska are examples
of the great expense and difficulty involved in new oil discovering.
Offshore drilling platforms extend the search for oil to the ocean's continental shelves- those gently sloping
submarine regions at the edges and the continental shelves - those gently sloping submarine
regions at the edges of the continents.
More than one- quarter of the world's oil and almost one- fith of the world's natural gas come from offshore,
even though offshore drilling is six to seven times more expensive than drilling on land.
A significant part of this oil and gas comes from under the North Sea between Great Britain and Norway.
24. Which of the following strategies for oil exploration is described in paragraph 4?
A) Drilling under the ocean's surface
B) Limiting drilling to accessible locations
C) Using highly sophisticated drilling equipment
D)Constructing technologically advanced drilling platforms
Answer: A
