III.
  1. 'Believe' is a sensing verb used to express the writer's opinion.
  2. 'Existence' and 'persistence' are nominalised forms of the verbs 'exist' and 'persist'. '-ence' is a common ending (suffix) for nominalisations. Nominalisations are also abstract nouns and these kinds of nouns are found in expositions which deal with ideas rather than concrete objects.
  3. Evaluative language which expresses an attitude or an opinion is found in expositions where the writer wants to convey his or her point of view. In this text there is clearly disapproval for the countries continuing to hunt whales. A more neutral way to express the idea would be to simply say: "Japan and Norway still continue their whaling for the purposes of scientific research."
  4. Modal verbs like 'must' 'can' and should are another way of indicating the writer's attitude.
  5. 'Therefore' is a connective. It shows the logical relationship between ideas in the text.
