Answer:
One sheave means that you are using a single drum winder. They are the worst! Double drum winders control easier, brake better and are much more efficient. They save time ( two skips or cages) and can be clutched to perform faster shift transport. A single drum is slow, unbalanced and can be a nightmare if it trips out during hoisting. If the brake system is not perfect it can be a real hairy experience. For a runaway single drum, there is no counterbalance effect. It always runs to destruction. With a double drum, the driver still has a chance to control the winder to a certain extent and he has two sets of brakes to rely on. A single sheave could also mean a shaft with a single compartment. No second means of escape unless there are ladders or stairways. Not a very healthy situation.
Those are just a few points. I am sure much more can be said in favor of a double drum winder and two or more sheaves in the headgear. Most of the shafts I have worked at have multiple winders and up to ten compartments. They all have a small single drum service winder for emergencies and moves of personnel during shift times. They are referred to as the Mary - Annes. Apparently, the name originated in the U.K. where an aristocratic mine owner named the first such winder after his mistress.

Answer:
All the three statements given are true so the correct option is option 4 which is none of the above.
Explanation:
The options are given in a jumbled up form the options are sorted which are as follows:
- SOA eliminates the use of application boundaries, the traditional methods where security is at the application level aren't likely to be effective
- An atomic service cannot be decomposed into smaller services that provide a useful function
- XML security service may be found in retail application communication.
- None of the mentioned
SOA stands for Service Oriented Architecture. This eliminates the application boundaries so option 1 is true.
An atomic service is defined as the smallest service which cannot be divided further. So this is true as well
The XML security service is incorporated in all retail applications. so this is true as well.
So the remaining option is just None of the mentioned.
