- Quantum computing, a rapidly emerging technology, harnesses the properties of quantum mechanics to store data and perform calculations using qubits rather than regular binary bits. Quantum algorithms take a new approach to numerous sorts of complex problems by creating multidimensional spaces linking data points. Our classical computers, even super computers can't do this. Quantum computers might contribute greatly to security, finance, aeronautics, bioinformatics, digital manufacturing etc. Real quantum hardware, a tool scientists only began to imagine three decades ago, is now available to millions of developers. Powerful super conducting quantum processors are driving towards such a computing speed and capacity that they can potentially change the world.Quantum algorithms can work ______.
- Throughout history, the search for salt has played an important role in society. Where it was scarce, salt was traded ounce for ounce with gold. Rome′s major highway was called the via salaria, that is the Salt road. Along the road, Roman soldiers transported salt crystals from the salt flats at Ostia up the Tiber River. In return, they received a salarium or salary, which was literally money paid to soldiers to buy salt. The old saying ‘worth their salt′.

- In 1992, the World Health Organization (WHO) reported that ten to twelve million adults and one million children worldwide had contracted HIV, the virus that causes AIDS, and they estimated that by the 21st century, forty million people would be infected. If the current trends continue, however, that estimate will fall far short of actual numbers, which may reach one hundred ten million. Beside people with high-risk behavior such as homosexuals, female sex workers, truck drivers and injection rates have begun to increase in the general population.In addition, there appears to be a change in the characteristics of AIDS victims. In the 1980s, homosexual men in large urban areas accounted for approximately two thirds of all AIDS cases. Women and children seemed to be in the periphery of the AIDS epidemic. But today almost 90% of new adult infections result from heterosexual contacts. Consequently, the rates of exposure and infection are rising for women, with and accompanying rise in the number of children born to them with HIV. In the 21st century it is expected that the majority of AIDS victims will be heterosexual women and their young children. According to the passage, the segment of the ___ with probably constitute, majority of AIDS cases in the 21st century

- Read the following article and answer the questionsAn earthquake is the result of a sudden release of energy in the earth's crust that creates seismic wave. Earthquakes are caused mostly by rupture of geological faults, but also by other events such as volcanic activity,landslides, mine blasts and nuclear tests.Earthquakes are recorded using seismometers and magnitude of the earthquake is measured by the Richter scale. The largest earthquakes in historic times have been magnitude slightly over 9. It is estimated that around 500,000 earthquakes occur each year, detectable with current instrumentations. About 100,000 of these can be felt. Most of the world's earthquakes (81% of the largest) take place in the 40,000 km long zone called the cirum-paific seismic belt known as the Pacific Plate. Massive earthquakes tend to occur along other plate boundaries too, such as along Himalayan Mountains.At the earth's surface,earthquakes manifest themselves by shaking and sometimes displacement of the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes can also trigger landslides and occasionally volcanic activity.Which of the following statements is incorrect?
