PTE Speaking & Writing Practice Test 9

"The laboratory results confirmed the researchers' initial hypothesis about the compound."

"Let's look today at how 3D printing, also called additive manufacturing, builds physical objects layer by layer directly from a digital design file. Unlike traditional manufacturing methods, which typically involve cutting, drilling or moulding material away from a larger block, additive manufacturing works in the opposite direction, depositing material only exactly where it is needed, one thin layer at a time, until the complete three-dimensional object has been built up. A digital design file is first mathematically sliced into hundreds or even thousands of extremely thin horizontal cross-sections, and the printer then builds each of these cross-sections in sequence, with each new layer bonding to the one beneath it. This layer-by-layer approach allows manufacturers to create remarkably complex internal structures, such as hollow lattices or intricate internal channels, that would be extremely difficult or entirely impossible to produce using traditional subtractive manufacturing techniques. Because a 3D printer can produce a single customised object as easily as producing many identical copies, the technology has proven particularly valuable for rapid prototyping, custom medical implants tailored to an individual patient's anatomy, and small-batch manufacturing where traditional mass-production tooling would be prohibitively expensive to justify."

"An astronomer." — one word is enough; a full sentence is not required.

Speaker A: "I think free university tuition should be limited specifically to STEM students, since science, technology, engineering and maths graduates fill critical skills shortages that directly benefit national economic growth."

Speaker B: "I understand the economic argument, but limiting free tuition to certain fields seems unfair to equally talented students in the humanities or arts, whose work also contributes meaningfully to society in less directly measurable ways."

Speaker A: "That's a fair concern, though targeted funding could still coexist with reduced, rather than fully free, tuition for other fields, balancing fairness with the practical need to address specific skills shortages."

Speaker B: "That's a reasonable compromise, though I'd add that skills shortages shift constantly, so today's STEM priority could easily become tomorrow's oversupplied field if funding decisions aren't regularly reassessed."

Moderator: "So we have one position favouring free tuition targeted specifically at STEM fields, and another favouring broader, fairer access with careful, ongoing reassessment of funding priorities."

শক্তিশালী: উভয় দৃষ্টিভঙ্গি বিস্তারিত, একটি বাস্তবসম্মত মিশ্র সমাধান প্রস্তাবিত।

মধ্যম: মূল ধারণা ঠিক আছে কিন্তু সহজ বাক্য গঠন, সীমিত শব্দভান্ডার।

দুর্বল: ব্যাকরণ ভুল অনেক, খুব কম শব্দ, স্পষ্ট গঠন নেই।
