Practice 3: Reading Passage

When Dr. Ayesha Malik submitted her research, she braced for rejection. The scientific establishment often rejected ideas that challenged accepted theory—and her conjecture about dark matter did exactly that.

The trajectory of her career had been unconventional. As a young scientist, she felt dejected after her first papers were dismissed. Colleagues would interject during her presentations with objections that felt personal. But she refused to let subjective criticism derail objective science.

"Don't subject yourself to their doubt," her mentor advised. "Project confidence. Inject your passion into every word. If they try to eject you from the conversation, object—but stay calm."

She followed that advice. When reviewers raised objections, she responded with data. When critics formed conjectures about her motives, she ignored them. Slowly, the trajectory of opinion shifted.

Years later, when her work was finally accepted, a reporter asked how she handled rejection.

"Every projectile faces resistance," she said with a smile. "The question is where you aim. If your trajectory is true, eventually you land."
