    Ecotourism now accounts for twenty per cent of tourists. It should provide a sustainable alternative to overuse of natural However, tourists may introduce new diseases to animal populations. Mongooses and meerkats in Botswana have died from tuberculosis caught from humans, and gorillas in East Africa picked up new internal parasites after the introduction of tourism. Moreover, the presence of humans in increased numbers has been shown to stress polar bears, penguins, dolphins and rainforest birds, affecting their natural routines and reducing breeding success.

    39. Which of the following can reliably be inferred from the above passage?
    • 0
    0

    Explanation

    The correct answer is E.

    The passage examines how ecotourism must offer a sustainable substitute to the overuse of natural resources, however it then also illustrates the range of problems that are associated or can be generated by this. These include a reduction in breeding success, stress and diseases. This suggests that the negative outcomes can outweigh the positive, and this is particularly supported by the fact that the passage indicates that ecotourism should offer an alternative that is sustainable, which holds an implication that indeed it doesn’t, therefore E can inferred reliably. Nothing can be inferred about the attributes of the changes observes such as altered behaviour patterns and new diseases, thus the recommendation that they may not be as obvious to a casual observer in A. cannot be confirmed from the passage reliably. The statements C. and D. are not relevant and we have no information, (for example, we cannot tell if the dolphins become frantic when they are near fishing boats) hence this is why neither C. and D. can be reliably inferred. B. also cannot be reliably inferred, this is due to the passage indicating that ecotourism projects are in fact not sustainable because of the damage caused to wildlife.
