Answer the following question: Clive Roberts,a director at ELS Educational Services,says English tests are changing greatly in response to the global growth in the use of English as _ -- the common language used among people with different native languages.For that reason,a lot of new tests are being developed while old tests are being improved to meet the needs of universities and employers worldwide. Changes in language testing "A lot of tests are now delivered online,all four skills are being tested,in some cases,by computer,in particular speaking and writing skills,which are the most difficult to assess on a computer environment,"says Mr.Roberts. Computer testing will reduce the length of time required for testing,because the tests adjust to the test-taker's ability.These computer-adaptive tests also increase accuracy in scoring.Computer-adaptive tests change depending on the test-taker's responses.They can become more or less difficult during the testing session.For this reason,the set of correct answers will be different for each test-taker. Cultural sensitivity Another change to language testing relates to cultural sensitivity.The term refers to material on a test that is based on a certain culture or is hard for test-takers from different cultures to understand.

The changes mean students have to be able to understand... Which words can best describe the new English tests? A) More accurate but easier. B) Less practical but harder. C) Better but harder.
