Reading Comprehension.
Variant II.
I. Read the text. Choose the correct answers.

Unlike most other children, Kyle Jameson was able to read at the age of two. He started writing at the age of three and reached Grade 7 on the violin by the age of five. At the staggeringly young age of fourteen he has just graduated from Oxford University and is the proud holder of an Honours degree in Physics. When Kyle was a pupil at primary school, he demonstrated an outstanding ability in science, progressing at a rate not previously seen by his teachers. His teacher suggested he take a general science exam intended for students in the first year of a degree course. Kyle took the test and passed with flying colours. As doing other subjects at school interfered with his ability to learn science, his teacher considered sending him to a secondary school specialising in science. However, Kyle’s parents wanted him to have a normal childhood. Kyle had severe problems with communication, which affected his popularity at school, but was ambitious and serious about his academic achievements, and at the age of ten completed three university modules in maths, physics and chemistry. At this point, his parents asked him to stop studying, but he was stubborn and enjoyed his unconventional lifestyle, so he decided to go to university. Despite his abilities and IQ level, several universities rejected him because they believed that at the age of ten he'd be far too immature to integrate with his much older fellow students. Some faculties were worried that they would be robbing him of his childhood years. He was asked to complete several IQ tests and psychological tests of his personality traits. In the end, Kyle was accepted by Oxford University, where he has just completed a physics degree. Intelligence is not Kyle's only natural gift, although his IQ is too high to be measured accurately. He is certainly considered a genius, but his passion for science does not dominate his life. He goes kayaking, performs on the violin at concerts and is also a dedicated singer in a choir. He takes everything he does in his stride. If you look beyond his messy appearance, spiky hair and piercing eyes, and if you ignore the fact that he is often described by his friends as grumpy and irritable, you will see a witty and extremely rational young man who has just started research in nuclear physics at the age of fourteen.
