A . Thread management inside the JVM process might be less effective than context switching between processes on the OS level. It is better to combine both these technologies to achieve full saturation of resources. B . Current CPUs are multicore units. So starting managed servers in the amount of physical cores and pinning them 1:1 to cores will always get the best performance. C . By a combination of prioritization of processes on the OS level and Work Manager in WLS, one  could tune the whole environment more precisely. D . Assigning more than one managed server to hardware will never bring better performance.  E . More instances means more connections to databases, so one could serve more concurrent calls on the database level. This is primarily why this approach will give better performance numbers.   F . Depending on the profile of the application, having more JVMs with smaller heaps will lead to more predictable response times than fewer JVMs with a large heap.

In the United Kingdom, about one in ten people have some disability. Disability is not just something that happens to other people: as get older, many of us will become less mobile, hard of hearing or have failing eyesight. Disablement can take many forms and occur at any time of life. Some people are born with disabilities. Many others become disabled as they get older. There are many progressive disabling diseases. The longer time goes on, the worse they become. Some people are disabled in accidents. Many others may have a period of disability in the form. of a mental illness. All are affected by people's attitude towards them. Disabled people face many physical barriers. Next time you go shopping or to work or visit friends, imagine how you would manage if you could not get up steps, or on to buses and trains. How would you cope if you could not see where you were going or could not hear the traffic？ But there are other barriers: prejudice can be even harder to break down and ignorance inevitably represents by far the greatest barrier of all. It is almost impossible for the able-bodied to fully appreciate what the severely disabled go through, so it is important to draw attention to these barriers and sow that it is the individual person and their ability, not their disability, which counts. The first paragraph points out that ______. A．there are many disabled people in the world B．the number of disabled people in India is the greatest C．India has much more disabled people than Canada D．it is impossible to get an exact figure of the world' s disabled people
