Dryland farming is the only way to not only combat recurring drought but also meet the increasing food requirements of Pakistan. About 45% of Pakistan’s total crop production now comes from drylands. By the end of this century, this will have to increase to 60% if Pakistan is to provide adequate food for projected population of one billion by the turn of the century. At present Pakistan gets larger food production from wetlands.

LOGICAL REASONING

Probably true Data inadequate Probably false Definitely false Definitely true

The space exploration has been done mainly by using unmanned satellites called space probes containing a large variety of latest scientific instruments on board. These space probes have provided us the close-up pictures and other data about planets and other bodies in the outer space. The climax of the intensive American space programme came when Nell Armstrong became the first man to set foot on the moon on July 20, 1969. Originally, the artificial satellites were launched for studying the upper atmosphere of earth. Space probes are provided with computers.

Logically these are rules of conduct. Every country has laid down comprehensive series of practical rules for citizens for resolving mutual contradictory rights and interests. Most of these rules have been laid down to sustain social activities. For instance, many countries have laid down rules to protest against such unsocial activities as theft, attack and murder. These rules are backed by judicial system and executory institutions, which look after the people who obey the rules and also who violate the rules. Wherever the human behavior is involved such rules are not only for namesake there but are necessary also. There are no rules in countries where citizens’ interests and rights do not contradict Probably true Data inadequate Probably false Definitely false Definitely true
