Read the following article and select the best answer. Article: Everywhere man is altering the balance of nature.He is facilitating the spread of plants and animals into new regions, sometimes deliberately, sometimes unconsciously.He is covering huge areas with new kinds of plants, or with houses, factories, slag-heaps and other products of his civilization.He exterminates some species on a large scale, but favours the multiplication of others.In brief, he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million. Many of these changes which he has brought about have had unforeseen consequences.Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade, or that the provision of pot cacti for lonely settlers' wives would have led to Eastern Australian being overrun with forests of Prickly Pear? Who would have prophesied that the cutting down of forests on the Adriatic coasts, or in parts of Central Africa, could have reduced the land to a semidesert, with the very soil washed away from the bare rock? Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa, measles into Oceania, very possibly malaria into ancient Greece? These are spectacular examples; but examples on a smaller scale are everywhere to be found.We make a nature sanctuary for rare birds, prescribing absolute security for all species; and we may find that some common and hardy kind of bird multiplies beyond measure and ousts the rare kinds in which we were particularly interested.We see, owing to some little change brought about by civilization, the starling spread over the English country-side in hordes.We improve the yielding capacities of our cattle; and find that now they exhaust the pastures which sufficed for less exigent stock. Question: What have spread diseases? - Disease-sleeping sickness. - Measles. - Improved communications. - Malaria.
Improved communications.

Q: Read the following article and select the best answer. Article: Vienna--Although Iraq's decided to stop oil deliveries , the 11-nation Organization of Petroleum Exporting Countries (OPEC) will not increase production to make up the shortfall caused by Iraq. The 11 oil ministers decided to meet again on July 3 to discuss the effects of the Iraq temporary stop. The organization's president Charkid Khelil of Algeria said after the meeting that stocks were high and prices were stable and that quota increases were not necessary. The EU Commission has also expressed concern about Iraq's output stop. A speaker said OPEC had to take all possible measures to keep or lower the oil price. Saudi Arabia's Oil Minister Ali Al-Nuaimi had earlier said that there would not be any shortfall of oil in the market. The organization had already taken steps to fill the gap , he said. OPEC Secretary General Ali Rodriguez added that the period of the Iraq stop to export was not known, so other exporters were not going to lift quotas yet. If the market was destabilized , a suitable response would be made. Iraq stopped delivery of crude oil on Monday to protest against the UN Security Council's decision to extend the oil-for-food program by only a month, instead of the normal six-month renewal . Just before the Vienna meeting, oil prices had gone up, with a barrel of OPEC crude selling for 27.05 dollars, up from 26.81 dollars last Friday. And north sea oil was at 29.26 dollars Monday evening. OPEC wanted the oil price to stay within a margin of 22 to 28 dollars and achieved that in January and March by reducing 2.5 million barrels per day off quotas. Question: Iraq made the decision to stop oil deliveries because _ . - oil price is too low in the international market - the UN Security Council had decided to shorten the time for the oil-for-food program - many oil wells were destroyed during the war - it couldn't get enough money to develop its economy
