Помогите, пожалуйста! Нужно ответить на вопросы по тексту:

Any citizen of the Russian Federation who has completed secondary education may apply to a medical school. Nowadays, the applicants submit the results of Unified State Exam or some categories of applicants are required to take entrance competitive examinations in biology and chemistry and the Russian language. Those who obtained the highest marks in the examinations are admitted. The instruction at higher schools is given through lectures, group instruction and practical classes. The majority of lectures have been recorded so that students can listen to them at any time that is convenient. The lectures that are on the timetable have been substituted for workshops where students can acquire practical skills. Nowadays, teachers often use the technology of Blended Learning, refer the students to Massive Open Online Courses to cover theory, Electronic testing is used as an assessment tool. The academic year begins on September 1st and is divided into two terms of four months each. At the end of each term the students have to pass a number of examinations. The course of study lasts 6 years and covers basic preclinical and clinical subjects. In the pre-clinical years, the curriculum is uniform for the students of such specialties as General Medicine, Preventive Medicine, Stomatology, and Pediatrics. During the first two years students study physics, general, organic, inorganic and biological chemistry. The students also study human anatomy, physiology, histology, microbiology, Latin, the English language as the language of medicine, and philosophy. Beginning with the third year, special clinical subjects are introduced - all branches of internal medicine, surgery, gynaecology, obstetrics, ophthalmology, infectious diseases and others. Students also take a number of practical training programs. This prepares them for performing their professional duties in future. In the course of practical training, they perform the duties of junior medical staff, then of nurses and after their fourth year, students take another practical course during which they are exposed to direct doctor-patient communication at the department of internal diseases, at the surgical department, and the department of obstetrics and gynaecology. Working as doctor's assistants, students master a definite number of medical and diagnostic procedures. Senior students also do a practical course in out-patient departments. They have to attend lectures, seminars, and clinical conferences as well. Medical students take a Final State Examination which includes theoretical questions in internal diseases, surgery and obstetrics and gynaecology, and in clinical cases. The graduates also have to demonstrate their practical skills. Those who have passed the examination receive their diploma, which qualifies them as doctors. After that, they have to take Certification Examination to have the right to practice medicine. Having received a diploma, they may take a two-year residency course qualifying them for practicing medicine as generalists or narrow specialists. Residents work under the direct supervision of experienced specialists in clinics and in major hospitals. Medical graduates can also apply for the post-graduate training. For three years postgraduates do research into one of the important problems of modern medicine, prepare a thesis, defend it, and obtain an academic degree of Candidate of Medical Science.
