“Được thư mẹ… Mẹ của con ơi, mỗi dòng chữ, mỗi lời nói của mẹ thấm nặng yêu thương, như những dòng máu chảy về trái tim khao khát nhớ thương của con. Ôi! Có ai hiểu lòng con ao ước được về sống giữa gia đình, dù chỉ là giây lát đến mức nào không? Con vẫn hiểu điều đó từ lúc bước chân lên chiếc ô tô đưa con vào con đường bom đạn. Nhưng con vẫn ra đi vì lí tưởng. Ba năm qua, trên từng chặng đường con bước, trong muôn vàn âm thanh hỗn hợp của chiến trường, bao giờ cũng có một âm thanh dịu dàng tha thiết mà sao có một âm lượng cao hơn tất cả mọi đạn bom sấm sét vang lên trong lòng con. Đó là tiếng nói của miền Bắc yêu thương, của mẹ, của ba, của em, của tất cả. Từ hàng lim xào xạc bên đường Đại La, từ tiếng sóng sông Hồng dào dạt vỗ đến cả âm thanh hỗn tạp của cuộc sống Thủ đô vẫn vang vọng trong con không một phút nào nguôi cả.”

(Nhật kí Đặng Thùy Trâm, NXB Hội Nhà văn, Hà Nội, 2005)

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer.

Why are we always pointing to Instagram as the cause of mental illness in our teenagers? It’s frustrating that abusive relationships, and the trauma they cause, are rarely mentioned in discussions about the prevalence of mental health problems in young people. Research by Women’s Aid and Cosmopolitan has found that a third of teenage girls have been in an abusive relationship. And, if that isn’t shocking enough, when the remaining two-thirds were asked further questions, it emerged that 64% of them had, in fact, experienced abusive behaviour – they just didn’t realise it was abuse.

Domestic abuse is normally associated with women cowering on the floor, as a violent husband waits to strike, or mothers covering up their black eyes with concealer before the school run. On the same day that the domestic abuse bill received its second reading in parliament, Age UK called for action to tackle domestic abuse of over-60s, whose needs it says are often overlooked by the law, policy and practice. The needs of teenagers in the heady throes of first love who are in emotionally abusive relationships also need to be recognised.

Common themes of such relationships include (though are not limited to) excessive jealousy, repeated criticism and sexual coercion. If your boyfriend or girlfriend is checking your phone, constantly asking to know your whereabouts, getting upset when you spend time away, turning up unannounced to surprise you, these are all examples of coercive control. If they never apologise in an argument and make everything your fault, tell you what you can and can’t wear, undermine you and/or publicly humiliate you under the guise of a “joke”, these again are common instances of controlling behaviour. Ditto, if they have a Jekyll/Hyde personality, make you feel like you are walking on eggshells even when things are seemingly going well, and threaten to hurt themselves if you leave. When it comes to sexual coercion and rape, examples include making you feel pressured to perform sexual acts you’re uncomfortable with, such as sending nude photos, having sex before you’re ready, being pressured to re-enact extreme sex from porn films or being told you don’t love them if you say no.

Often the victim in an abusive relationship can never quite put their finger on one thing, but the overwhelming feeling is of a general unease, feeling unsafe, defective, wrong, scared and as if you are going crazy. It’s your “yourselfness” that’s being consistently undermined, controlled and attacked by the person who claims to love you.

Which of the following is closest in meaning to “prevalence” as used in the passage?

Read the following passage about home schooling in the UK and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

Full-time education in the UK is compulsory from the age of five to sixteen, but this doesn’t have to be in a school. Around 50,000 children are educated at home. This is called ‘homeschooling’.

 Parents take their children out of school for different reasons, like illness and the need for special care, or because the distance to the nearest school may be too far. Some children are simply unhappy at school. Whatever the reason, they’re allowed to study at home, although inspectors regularly check how they are getting on.

 Hayley and Jenny haven’t been to school for two years but they haven’t neglected their studies. Their mother worked out strict timetables for them, with hourly lessons for each day. She’s responsible for teaching them Maths, English, History and French. Their father teaches them Science and Geography. They study all the other school subjects online. ‘We have lessons with Dad in the evenings and at weekends,’ explains Hayley.

 The family’s home is in a remote part of Wales. ‘The girls were fine at school but they spent so much time getting to school, they were too tired to learn, says their mother, Julia”. ‘We had a family conference and in the end we decided to try homeschooling. So far, it’s been a big success, but the girls know that if they want to go back to school at any time, we’ll let them. We follow the normal school program of lessons, and they will take all the normal school exams.’

 There are disadvantages too, of course. ‘Social isolation is something I worry about,’ says Julia. They both seem happy and well-adjusted, but they haven’t really got friends who live locally. But in the summer holidays they go away on trips to summer camps, where they have no trouble mixing with people and making friends.’

In which paragraph does the writer discuss the challeges associated with home scholling?
