Alpine tunnels are closed tunnels. In the past 30 yrs not even a single accident has been recorded for there is one accident in the railroad system. Even in case of a fire accident it is possible to shift the passengers into adjacent wagons and even the living fire can be detected and extinguished with in the duration of 30 min.

no accident can occur in the closed tunnels (True/False/Can't Say)fire is allowed to live for 30 min.(True/False/Can't Say)All the care that travel in the tunnels will be carried by rail shutters.(True/False/Can't 

In the past helicopters are forced to ground or crash because of the formation of the ice on the rotors and engines. A new electronic device has been developed which can detect the water content in the atmosphere and warns the pilot if the temperature is below freezing temp about the formation of the ice on the rotors and wings.

the electronic device can avoid formation of the ice on the wings (True/False/Can't Say)There will be the malfunction of rotor & engine because of formation of ice (True/False/Can't Say)The 

 Confucius said that to know the future we have to understand the past his time transport ,communications and scientific knowledge were less developed than they are today. News took weeks to travel where as today satellite links connect the continents virtually instantaneously. But our technological advances in the field of communications seem not to have improved our capacity to understand one another.

in Confucius day people were more intelligent   (True/False/Can't say)We understand each other better now than in Confucius time because we can travel more quickly (True/False/Can't 

Statistics show that millions of vehicles have been carried by shuttle over the past 30 years through alpine tunnels without one ever catching tire. In the alpine tunnels. Drivers and passengers sit in their vehicles on the shuttle trains. Only one vehicle has ever caught fire on the busy French monorail equivalent system. This sort of accidents is not possible in a closed shuttle. Assertions that a vehicle fire  will lead to catastrophe have no basis. since the resources exit do detect, control

If a car caught fire in a rail shuttle, probably none would be killed. (True/False/Can't say)At least one vehicle has caught fire in an alpine tunnel.(True/False/Can't say)If a fire started in 

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 

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
