The last two northern white rhinos on Earth appeared mournful during a memorial held for the final male of their kind as the species stands on the edge of extinction.
    Sudan, 45, died last month after suffering from a degenerative muscle and bone condition linked to age which left him unable to stand up.
    Sudan’s death should spell the end of his subspecies, but scientists have gathered genetic material and hope to develop IVF techniques to produce more white rhinos.
    He is survived by the last two females of his species, his 27-year-old daughter Najin and 17-year-old granddaughter Fatu.
    The pair appeared sad when they attended a memorial service for Sudan, whose death has led a Kenyan government official to declare anyone caught possessing ivory should be sentenced to life in prison.
    "Ivory belongs to elephants and rhinos," said Najib Balala, Kenya’s tourism minister. "We are going to change our laws so that anyone caught with ivory will be jailed for life. "
    Questions 1 and 2 are based on the news report you have just heard.
    1. What can we learn about the rhino Sudan?
    2. Why did scientists gather Sudan’s genetic material when he died?
