Read the following passage and mark the letter A, B, C, or II to indicate the answer to each of the question.

As Hurricane Florence zeroes in on the southeastern US, scientists are warning that climate change is exacerbating the effect of tropical storms. The powerful Category 4 Atlantic weather-front is slow moving, an increasingly common phenomenon that poses a different manner of threat to states in its path. In the event that Florence stalls or comes to a halt altogether over land, it has the potential to deposit catastrophic quantities of rainwater, posing a risk of severe flash flooding.

While the high winds and waves generated by faster storms moving inland from the ocean pose a significant danger to human life and property, the effect of heavy rain can be just as devastating, if not more so. When Hurricane Harvey hit in August 2017, it dropped 60 inches of rain over Houston, Texas, flooding the streets, leaving 93 dead and hundreds more having to be rescued by boat, causing millions of dollars-worth of damage.

James Kossin of the National Oceanic and Atmospheric Administration published a study in the journal Nature in June suggesting that slow-moving tropical cyclones, which would include those like Florence and Harvey, have become more common over the last 70 years, dropping in speed by 10 per cent in that time. According to Mr Kossin, global warming as a result of man-made air pollution is causing the poles to become warmer, which in turn reduces the difference in temperature between the Arctic and Antarctic and the equator, altering atmospheric pressure and slowing down the whipping currents of wind that pass between them and drive hurricanes.

The best title for this passage could be _______________.

Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question.

As computer use becomes more common, the need for security is more important than ever. One of the greatest security threats in the online world is computer hacking. Computer hacking is the unauthorized access to a computer or network of computers. Hackers are people who illegally enter systems. They may alter or delete information, steal private information, or spread viruses that can damage or destroy files. But how exactly can a hacker get into a system to do these things?

Most hackers use information called protocols that are built into computer software. These protocols allow computers to interact with one another. Protocols are sort of like computer police officers. When a computer connects to another system, the protocols check to see if the access is valid. The protocols can also determine how much information can be shared between the two systems. Hackers can manipulate the protocols to get unlimited access to a computer system.

In fact, just the act of entering a computer network is considered hacking. This is commonly called passive hacking. Passive hackers get a rush from just being able to access a challenging system like a bank or military network. Another kind of hacker tries to do damage to a system. After hacking into systems, these hackers release viruses or alter, delete, or take information. Known as active hackers, they are, by far, the more dangerous of the two.

        The easiest way to protect a system is with a good password, Long and unusual passwords are harder for hackers to guess. For even greater security, some online services now use “password-plus” systems. In this case, users first put in a password and then put in a second code that changes after the user accesses the site. Users either have special cards or devices that show them the new code to use the next time. Even if a hacker steals the password, they won't have the code. Or if the hacker somehow gets the code, they still don't know the password.
