Hacking is a crime made possible by a relatively new technology, which one of the reasons it is often poorly understood and reported. Many computers, but no means all, are now linked together in networks which allow users on one computer to communicate with others on the same network. If a computer is not networked, no manipulation of its data from another machine is possible. So long as users are authorized, networking is just a way of making work easier and more productive. Hacking on the other
Most hackers are authorized to break into networks (True/False/Can't say)Computers are only vulnerable to the unauthorized manipulation of their data via another computer if they are networked
Although invaders represent a threat to the conservation of flora and fauna, there are two special cases in which invasion have been deliberately brought about. One is the desire to control presents by natural predators, which may have to be brought in from other countries. The second is releasing organisms into the wild(or on to farms, from which they might escape)that are completely novel, because they have been genetically engineered. There is nothing intrinsically sinister about engineered organisms
Pest control does not threat the conservation of flora and fauna. (True/False/Can't say)Genetically engineered organisms must always be regarded as potentially dangerous. (True/False/Can't
Electronics technology is coming to the rescue of helicopters which can be grounded or crash in icy conditions the machines are especially vulnerable to the build up of ice on both their rotors and engine air intake when operating in cold damp conditions. the problem is 2 fold ice increases the weight and the build up makes the aerofoils less efficient .now at last a detector has been devised which the company hopes will means after flights and less frequent grounding. unlike most devices in use
an electronic device has been invented which will prevent he build up of ice on helicopter rotors (True/False/Can't say)helicopters are sometimes grounded because in cold damp weather
Anyone whose has systematically examined faces will have perceived a preponderance although not a proliferation of asymmetry. whether or not the expression is volitional and self controlled or spontaneous appears to predict facial asymmetry as does the type of emotion protrayed. positive emotions are usually displayed symmetrically although a left sided representation of a negative emotion is more common. posed expressions and negative emotions are less likely to be symmetrically represented.
an angry person is more likely to have a lopsided expression than someone who is smiling (True/False/Can't say)a deliberately assumed facial expression will always be asymmetrical (True/False/Can't
Human existence is not susceptible of arbitrary division between consciousness and unconsciousness. the conscious world invades and shapes the activities of the unconscious while many of the great achievements of humanitys waking hours were wholly or partly inspired by dreams even if it could be argued that dreams precede experience such a dichotomy could not be drawn as the influence of dreaming on the waking state would remain unclear but as yet no common vocabulary exists to record the substance
sleep can be a creative state. (True/False/Can't say)it is difficult to tell whether a sleeper is dreaming or not (True/False/Can't say)if we knew what babies dream about before
Disease x succeeds lung disease. it may also occur healthy persons the person looks healthier from outside. the number of red blood cells in the blood increased and this leads to thickness of the blood as a result of which blood lacks inside the vessels .the person suffers heart attack. one possible solution is to remove a liter of blood or to control the growth of red blood cells.
lung disease precedes the disease x (True/False/Can't say)a person who gets heart attack always has disease x (True/False/Can't say)people suffering from disease x look
A star fire engine has been designed to work only for unleaded petrol. this crossfire engine is designed for both 1500 and `1800 cc. they internally and externally look alike except for the difference in wheels. 2000 cc is different from the above two in terms of 3 features on the bumper.
the engine runs only on the leaded petrol (True/False/Can't say)1500 and 1800 cc look alike (True/False/Can't say)internal structure of the 2000cc is same as that of both
A weed killer to kill the weeds has been developed. the weed killer solution has to be applied to the growing tips. it need not to be applied to all the tips. the solution has to be prepared in a can in one hand and the plants are taken in the other hand with a glove and are immersed in the solution if we cannot immerse them in the solution the solution can be applied to the roots with a brush. it used without care it can pose danger to other plants.
the solutions has to applied to growing leaves (True/False/Can't say)to use the weed killer first take the plants in the can as then pour the solution into it.(True/False/Can't say)it is sufficient
