Smothered in haze, the trees couldn’t【C1】________fruit, leaving resident fruit bats with no other option than to fly elsewhere in search of food, carrying with them a deadly disease.
    Not long after the bats【C2】________on trees in Malaysian orchards, pigs around them started to fall sick—【C3】________after eating fallen fruit the bats had bitten—as did local pig farmers. By 1999, 265 people had developed a severe brain inflammation (炎症), and 105 had died.
