Inside a bustling ant colony, the life of a single worker ant is incredibly (21) __________. As a female ant that does not reproduce, her entire existence is dedicated to serving her colony and its single, most important member: the queen. The queen's only job is to lay eggs, ensuring the future of the colony. In contrast, a worker ant has many different responsibilities, which often change as she gets older. The entire colony works together like a superorganism, where each individual has a specific purpose.

One of the most common jobs is to forage for food. Worker ants often leave the safety of the nest to look for seeds, small insects, or sweet nectar. This task is dangerous, but it is essential for survival. Each ant is responsible (22) __________ specific tasks that help the group, and foragers must work hard to find enough food to feed everyone back in the nest, including the queen and the young larvae. They use special chemical signals called pheromones to create trails that lead other ants to the food source.

Foraging is a primary duty. (23) __________, a worker ant's job doesn't end there. Many workers are also builders. They use their strong jaws to dig new tunnels and expand the nest, creating a complex underground city. They also carry out maintenance duties, removing waste and repairing any damage to the tunnels. If a tunnel collapses, repairs must be made immediately to ensure the safety and efficiency of the colony's home.

Another vital role is caring for the young. After the queen lays her eggs, worker ants, sometimes called 'nurse' ants, take over. They move the eggs to special nursery chambers where the young are kept safe and warm. These 'nurse' ants carefully clean the eggs and help to raise the young larvae once they hatch, feeding them and protecting them from any danger. This ensures that the next generation of workers is strong and healthy.

From finding food to building the home and raising the young, the worker ant is the backbone of the colony. While she may be just one ant among thousands, her hard work is essential. Every single worker ant (24) __________ a vital role in the survival and success of the colony. The complex society of ants is a perfect example of how teamwork allows a community to achieve remarkable things.

Budget airlines have dramatically reshaped global travel. [I] These low-cost carriers offer affordable airfares by stripping away many traditional services. Before their emergence, air travel was often a luxury, accessible to few. [II] This no-frills model has democratized flying, making it a viable option for more budgets and truly opening up the possibility of seeing more of the world.

The impact of this revolution is particularly evident in Vietnam. Airlines like Vietjet Air have played a pivotal role in making regional and domestic air travel incredibly affordable. This accessibility has spurred a remarkable boom in tourism, especially among youth and families. [III] Popular destinations like Da Nang's stunning beaches or Phu Quoc island are now within reach for many, allowing more Vietnamese families to explore their beautiful country or even venture to neighboring nations without breaking the bank.

For young people aged 14-15, this shift in travel economics carries significant personal relevance. [IV] Imagine the possibility of more family vacations, exploring new cultures, or visiting distant relatives more frequently. Budget airlines can turn what might have been a once-in-a-lifetime trip into a regular occurrence. This newfound affordability means you might gain invaluable experiences, from tasting unique street food in another city to understanding different ways of life, all thanks to reduced travel costs.

However, embracing the budget airline experience requires understanding its trade-offs. The "no-frills" approach means paying extra for things standard on full-service carriers. This includes checked baggage, specific seat selection, and even onboard snacks. Legroom can be more limited, and flight schedules might be less flexible. To truly maximize savings, it’s crucial to read the fine print, pack lightly, and only pay for services you genuinely need. Ignoring details can quickly erase any initial fare advantage.

Ultimately, budget airlines are a powerful tool for unlocking greater travel opportunities. They have fundamentally changed the landscape of exploration, making it less about luxury and more about accessibility. For an adventurous teen, learning to navigate low-cost carriers effectively means more than just saving money; it means gaining the freedom to embark on more adventures, create lasting memories, and expand your horizons. With smart planning, the secret to seeing more of the world truly lies in understanding how to make budget travel work for you.
