Cameron is a West African country of ten million people which has been very successful in growing food for its people, unlike many other West African countries. Since 1971, it has doubled its output of major foodstuffs such as maize and potatoes. Now, it is one ofthe few African countries which is able to feed itself. This was not the case five years ago when the country was only 75-80% self-sufficient in food. Although isolated pockets of hunger still remain, the World Bank nowadays gives Camero financial aid to sustain, not to achieve, self-sufficient in food production.
Scientists estimate the Earth’s age by measuring the ratios of various radioactive elements in rocks. The oldest Earth’s rocks tested thus far are about 3 1/3 billion years old. But no one knows whether these are oldest rocks on Earth. Tests on rocks from the moon and on meteorites show that these are about 4.6 billion years old. Scientists believe that this is the true age of the solar system and probably the true age of the Earth.
2. According to this passage, how do scientists estimate the age of the Earth?
Dear Melissa,
I hope you are well. Guess what! I am having a big party next week at my house and I am inviting all my close friends. The theme of the party is going to be Harry Potter, so all must dress accordingly. You would make a great witch! I need to let everyone know by Wednesday since I am throwing the party next Saturday. Sam is going to decorate the house and my mother is going bake a cake and make lots of food. There is going to be music and dancing as well. John is going to be the DJ. You can stay over at my house. It’s going to be great! I hope to see you then.
Love,
Sarah
