Air pollution levels in Vietnam the past few weeks have reached alarming levels, prompting the government to issue advisories asking people to stay indoors and limit outdoor activities. While it is common to see people wearing face masks, the advisory mentioned that masks should be worn along with eye glasses when outside. It further warned that levels of Particular Matter (PM) 2.5, which are harmful when breathed, would remain high. The highest Air Quality Index (AQI) levels were recorded in the capital Hanoi, which recorded an AQI on 272 on September 30, exceeding the unhealthy levels, while Ho Chi Minh City recorded an AQI of 153. On September 27, Hanoi momentarily was recorded as the most polluted city in the world, as per the IQAir AirVisual monitoring app. Residents complained that Landmark 81, the tallest building in Ho Chi Minh City, which is usually clearly visible, was shrouded in haze. Several media outlets also discussed the topic and recorded several pictures of haze shrouding the city. But air pollution is more than just a nuisance. When air quality conditions deteriorate, the government will take action to curb polluting industries and practices. Meanwhile, employers need to take additional measures to ensure that their operations and staff are not unduly affected. 2. If the issue worsens, recruiters may find it more challenging to source top-level talent, particularly in Hanoi and Ho Chi Minh City, which typically receive the lion\u2019s shar e of foreign investment.

Question 36 \u2013 40: Read the passage carefully. Marriage is an ancient religious and legal practice celebrated around the world. However, wedding customs vary from country to country. The Wedding Dress: In many countries, it is customary for the bride to wear a white dress as a symbol of purity. The tradition of wearing a special white dress only for the wedding ceremony started around 150 years ago. Before that most women could not afford to buy a dress that they wear once. Now, bridal dresses can be bought in a variety of styles. The Wedding Rings: In many cultures, couples exchange rings, usually made of gold or silver and worn on the third finger of the left or right hand, during the marriage ceremony. Flowers: Flowers play an important role in most weddings. Roses are said to be the flowers of love, and because they usually bloom in June this has become the most popular month for weddings in many countries. After the wedding ceremony, in many countries the bride throws her bouquet into a crowd of well-wishers - usually her single female friends. The person who catches this bouquet will be the next one to marry. Gifts: In Chinese cultures, wedding guests give gifts of money to the newly-weds in small red envelopes. Money is also an appropriate gift at Korean and Japanese wedding. In many Western countries, for example in the UK, wedding guests give the bride and groom household items that they may need for their new home. In Russia, rather than receiving gifts, the bride and groom provide gifts to their guests instead. With the continued internationalization of the modern world, wedding customs that originated in one part of the world are crossing national boundaries and have been incor por ated into marriage ceremonies in other countries. Choose an option (A, B, C or D) that best answers each question. 36. The word \\\"incor por ated\u201d in paragraph 6 mostly means . A. given B. integrated C. brought D. separated 181 \/ 407","37.
