PTE Speaking practice questions in the real exam format and timing.
Antibiotic resistance occurs when bacteria evolve mechanisms to survive drugs that once killed them. Health authorities warn that overuse of antibiotics in both human medicine and livestock farming is accelerating this process, potentially returning society to an era when minor infections could become fatal.
Vaccines work by introducing a weakened or inactivated form of a pathogen into the body, prompting the immune system to produce antibodies without causing disease. This preparation enables a faster and stronger response if the same pathogen is encountered naturally in the future.
Early diagnosis of chronic diseases such as diabetes and hypertension significantly improves patient outcomes. Regular screening programmes allow healthcare providers to detect warning signs before symptoms appear, enabling interventions that can delay or even prevent the most serious complications of these conditions.
A drug that performs well in trials may disappoint in practice. Trial participants are selected, monitored and reminded to take their medication, while ordinary patients juggle several prescriptions, side effects and busy lives, and the gap between the two settings is often substantial.
Placebo effects are real physiological events rather than imagination. Expecting relief changes the release of the body's own painkillers, which is why trials must compare a new drug against an inactive treatment rather than against nothing at all.
