Read the passage below and choose A, B, C or D to fill in each blank.

There are more than one billion cows in the world, and cow farming is a large source of methane emissions. This colorless and odorless gas (631) ____ at warming the earth.

Farmers and companies are developing solutions for (632) _____. In Canada and Brazil, farmers started adding a special ingredient to their animals' feed to reduce cows' methane production. In New Zealand, scientists are working on a vaccine which can cut methane emissions. Rather than stopping methane emissions, a UK company has designed face masks to catch the gas (633) ______.

The masks will allow cows to continue their normal diet but will turn methane into CO2 and water. They can fit comfortably on the cow's head and can be adjusted to different head sizes. Sensors on the masks can notice when methane comes out of the cow's mouth and provide the percentage of the gas (634)_____. This information can also be useful for farmers who can use it to (635) __________ the early signs of disease. For example, if a cow eats less, but produces more methane than usual, it may have a health problem.

It is predicted that the need for beef and dairy products will go up in the coming years. The company developing the methane-catching masks hopes that farmers will start using their invention, which will slow down global warming.

Read the following passage about human life expectancy 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.

In the UK, comprising England, Scotland, Wales, and Northern Ireland, jokes and tricks can be played until noon on 1 April. After midday it's considered bad luck to play a trick. Anyone who forgets this and tries a joke in the afternoon becomes an 'April Fool' themselves.

So, what kind of jokes do people play? Well, a simple example would be telling your friend that their shoelaces are undone. Then, when they bend down to do them up, you shout, 'April Fool!', and they realise their shoelaces are fine.

Maybe it's not your kind of humour, but watch out, there's always someone who will find it funny! In Ireland, a popular prank is to send someone on a 'fool's errand'. The victim is sent to deliver a letter, supposedly asking for help. When the person receives the letter, they open it, read it and tell the poor messenger that they will have to take the letter to another person. This continues and the victim ends up taking the message to several different people until someone feels sorry for them and shows them what the letter says: 'Send the fool to someone else.'

In France, Belgium, the Netherlands (or Holland), Italy and French-speaking areas of Canada and Switzerland, the 1 April tradition is known as the “April Fish”. A common joke is to try to stick a paper fish onto a victim's back without being noticed.

Read the following passage about the Designing Spaces That Connect Us to Nature 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 31 to 40.

Biophilic design has been turning heads and winning hearts by incorporating natural elements into our living and working spaces. This approach recognizes our innate connection to nature and how it affects our well-being. Studies show that exposure to natural light, plants, and natural materials can reduce stress and improve productivity. Many modern architects now integrate gardens, water features, and large windows into their designs. These elements help create environments where people can thrive both mentally and physically. As one designer put it, "We're bringing the outside in to help people feel at home in their skin."

The benefits of biophilic design extend beyond aesthetics. [I] Hospitals with views of nature report faster patient recovery times. Office buildings with natural elements see decreased absenteeism and increased worker satisfaction. [II] Schools incorporating biophilic principles observe improved student concentration and academic performance. [III] Even retail spaces benefit, with customers spending more time and money in naturally-designed environments. These practical advantages explain why biophilic design is gaining momentum across various sectors. [IV]

Implementing biophilic design doesn't require elaborate renovations. Simple changes like adding houseplants, using natural materials, or rearranging furniture to maximize natural light can make significant differences. Even artificial representations of nature, such as nature photography or recordings of birdsong, provide some benefits. The key is creating spaces that stimulate our senses in ways that remind us of natural environments. This approach works in urban apartments, suburban homes, and rural settings alike. As cities grow denser, these natural connections become increasingly valuable for maintaining our psychological health.

Looking ahead, biophilic design will likely become standard practice rather than a luxury option. Climate change concerns are pushing architects to create buildings that not only connect with nature but also protect it. Living walls that purify air, rooftop gardens that reduce energy consumption, and materials that sequester carbon are becoming more common. These innovations represent a shift from merely appreciating nature to actively participating in its preservation. By designing spaces that honor our biological need for natural connection, we create environments that support both human and planetary health for generations to come.
