A black hole is a region of space where gravity is so strong that nothing can escape, not even light. Most form when a mass star runs out of fuel and collapses inw. Because black holes emit no light, astronomers must det them indir. One method is to obse stars that orbit an invisible obj at extraordinary speed. Another is to meas the X-rays given off by hot gas as it spir toward the edge. In 2019, scientists finally prod a direct image of the glowing mate surrounding one.

Read an Academic Passage

Read the passage and answer the questions.

Skeletal muscle contraction depends on a precise molecular mechanism known as the sliding filament model, in which two types of protein filaments, thick filaments made of myosin and thin filaments made mostly of actin, interact within a muscle fibre to generate force without either filament actually changing length. When a nerve signal triggers contraction, calcium ions flood into the muscle cell and bind to a regulatory protein, exposing binding sites on the actin filament. Myosin heads, powered by energy released from ATP, then attach to these exposed sites, pull the actin filament a short distance in a motion often compared to rowing, release, and reset to repeat the cycle, with thousands of these tiny pulling actions occurring nearly simultaneously along the muscle fibre to produce a smooth, continuous contraction rather than a series of small jerks. This repeated cycling causes the overlapping filaments to slide past one another, shortening the overall muscle fibre even though the filaments themselves remain the same length throughout. When ATP is unavailable, as occurs after death, myosin heads remain locked onto actin, unable to release, producing the temporary muscle stiffening known as rigor mortis. Muscle fatigue during intense exercise arises from a related but distinct set of factors, including depleted calcium signalling efficiency and the buildup of metabolic byproducts that interfere with this cycle.

5. According to the passage, what triggers calcium ions to enter a muscle cell?

6. As used in the passage, "cycling" refers to

7. What can be inferred about rigor mortis, based on the passage?

8. Why does the author compare the myosin motion to "rowing"?

9. What is the main idea of the passage?

Write an Email

Write an email that responds to the situation.

Your team at work has been asked to give a presentation, but you cannot attend the rehearsal. Write an email to your team leader, Sam. In your email, do the following: - Explain why you cannot come. - Offer another way to prepare. - Ask about your role.
Show sample answer
Model answer: Hi Sam, I'm sorry, but I won't be able to come to Wednesday's rehearsal. I have a dentist appointment that I cannot move, because I have been waiting for it for two months. I don't want to slow the team down, so I would be happy to run through my part with you on Tuesday afternoon or by video call on Wednesday evening. I will also send you my slides tomorrow so that you can check them. Could you also remind me exactly which sections I will present? I think it was the market analysis and the summary, but I would like to be sure. Thanks for understanding. Best, Karim

Write for an Academic Discussion

Read the discussion and write a post that contributes to it.

Professor Bergqvist: In sports economics, college athletes in some countries generate millions of dollars for their universities through ticket sales and media deals, yet traditionally receive no direct salary. Should college athletes be paid a wage for playing? Delphine: Yes, pay them. It's exploitative for a university to earn millions from a student's performance and image while that student can't even accept a paid sponsorship without risking their eligibility. Rowan: I'm hesitant. Paying athletes could turn college sports into a purely commercial enterprise, widen the gap between rich and poor athletic programmes, and complicate athletes' status as students rather than employees. Write a post that contributes to the discussion (at least 100 words).
Show sample answer
Model answer: I lean towards Delphine's fairness argument, mainly because the scale of revenue some college sports programmes generate makes the current unpaid arrangement look increasingly hard to defend on principle, especially when coaches and universities profit enormously from the same performances. Rowan's concerns about commercialisation and inequality between programmes are worth taking seriously, though, rather than dismissing as simply resistance to change. I would support allowing athletes to earn money from endorsements and their own image and likeness, which several places have already introduced, as a middle step, while being more cautious about universities themselves paying direct salaries, since that shift really could accelerate the commercial pressures and inequality Rowan is worried about.
