Read the following passage about Wildlife Conservation in Africa 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.

Wildlife conservation in Africa is vital for preserving biodiversity and ensuring the survival of iconic species such as elephants, lions, and rhinos. [I] The continent is home to some of the world’s most diverse ecosystems, including savannahs, rainforests, and deserts. [II] Conservation efforts involve strategies like protecting habitats, combating poaching, and raising awareness about the importance of wildlife. [III] Despite challenges, success stories demonstrate the positive impact of these efforts. [IV]

One notable example comes from Kenya, where anti-poaching initiatives and community engagement have helped stabilize elephant populations in Amboseli National Park. Similarly, in South Africa, rhino conservation programs use advanced technologies like drones and GPS tracking to monitor and protect vulnerable animals. These efforts not only safeguard wildlife but also promote eco-tourism, which supports local economies.

However, wildlife conservation in Africa faces persistent threats. Habitat loss due to agricultural expansion and urbanization continues to endanger species. Climate change exacerbates these challenges, altering migration patterns and threatening ecosystems. Furthermore, poaching and the illegal wildlife trade remain significant concerns, driven by global demand for products such as ivory and rhino horn.

To overcome these challenges, conservationists emphasize the need for international collaboration and local community involvement. Initiatives like eco-tourism provide financial incentives for communities to protect wildlife. Governments, NGOs, and individuals must work together to ensure the survival of Africa’s unique species for future generations.

Read the passage 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 7 to 14.

The concept of project farming, where farmers come together to collaborate on large-scale agricultural projects, has gained significant traction, and modern technology keeps this collaboration on track. Advanced technologies such as GPS, sensors, drones, and data analytics are used to optimise agricultural practices. Additionally, the collected real- time data on soil conditions, weather patterns, and plant growth enables farmers to accelerate the decision-making process that maximises productivity while minimising resource wastage.

GPS technology allows farmers to precisely map out their fields and create customised planting plans. This ensures that seeds are sown at optimal locations based on soil characteristics and previous yield data. By avoiding areas with poor fertility, farmers can increase their overall crop yield. Camera traps provide advance warnings of insects, so farmers do not have to treat the whole field. This, therefore, helps curb chemical runoff and save money for every party involved in the project.

Technology also plays a vital role in optimising irrigation practices for sustainable agriculture. Specialised equipment reports dryness hour by hour, and weather apps forecast rain for the week ahead. Automated valves give each zone exactly the water it needs and pause when clouds are approaching. This cuts pumping costs and protects groundwater while keeping the crop healthy. On dry continents, such savings keep projects economically viable.

The digital trail does not stop at the farm gate. Cloud platforms let project farmers, processors, and truck drivers input harvest weights, storage temperatures, and delivery times the moment they change, while blockchain records freeze each entry so customers can trust it. Analytic tools combine seasons of records to forecast demand, spot price opportunities, and mark weak points in the workflow. This allows project farmers to anticipate market demand, exploit resource allocation, and plan for potential challenges.
