Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
Lead poisoning in children is a major health concern. Both low and high doses of paint can have serious effects. Children exposed to high doses of lead often suffer permanent nerve damage, mental retardation, blindness, and even death. Low doses of lead can lead to mild mental retardation, short attention spans, distractibility, poor academic performance, and behavioral problems.
This is not a new concern. As early as 1904, lead poisoning in children was linked to lead– based paint. Microscopic lead particles from paint are absorbed into the bloodstream when children ingest flakes of chipped paint, plaster, or paint dust from sanding. Lead can also enter the body through household dust, nailbiting, thumb sucking, or chewing on toys and other objects painted with lead–based paint. Although American paint companies today must comply with strict regulations regarding the amount of lead used in their paint, this source of lead poisoning is still the most common and most dangerous. Children living in older, dilapidated houses are particularly at risk.
What does the author imply in the final sentence of the passage?
A. Old homes were painted with lead – based paint
B. Lead–based paint chips off more easily than newer paints
C. Poor people did not comply with the regulations
D. Old homes need to be rebuilt in order to be safe for children

Dịch bài
Ngộ độc chì ở trẻ em là một vấn đề sức khoẻ nghiêm trọng. Đã gọi là sơn thì liều lượng cao hay thấp đều có thể gây hậu quả nghiêm trọng. Trẻ tiếp xúc với chì ở liều lượng cao thường bị tổn thương lâu dài về thần kinh, thiểu năng trí tuệ, mù mắt, thậm chí mất mạng. Nhiễm chì mức độ thấp thì có thể thiểu năng trí tuệ ch t ít, kém tập trung, dễ xao lãng, kết quả học tập kém và có vấn đề về hành vi ứng xử.
Đây không phải là một mối quan tâm mới. Ngay từ đầu năm 1 04, tình trạng trẻ bị nhiễm chì đã được cho là có liên quan tới sơn có chì. Hạt chì li ti trong sơn sẽ thấm vào máu khi trẻ nuốt phải những mảnh sơn, vữa bị tróc hoặc bụi sơn trong cát. Chì cũng có thể xâm nhập cơ thể qua bụi bặm trong nhà, do trẻ cắn móng tay, mút tay hoặc nhai đồ chơi và những món đồ nào sơn bằng sơn có chì. Mặc dù hiện nay các hãng sơn của Mỹ phải tuân thủ các quy định nghiêm ngặt về lượng chì dùng trong sơn, nhưng sơn vẫn là nguồn gây nhiễm độc chì phổ biến nhất, nguy hiểm nhất. Đặc biệt là trẻ sống trong những ngôi nhà cũ đổ nát thì càng dễ bị nhiễm chì hơn nữa.
