Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.
Robots are useful for exploring and working in space. In particular, many robots have been sent to explore Mars. Such robots have usually looked like a box with wheels. Though these robots are useful, by their very nature they are unreliable, extremely expensive, and they break easily. Also, they cannot do very many tasks. Because of these problems, scientists have been developing a new and unusual kind of robot. These new robots move like snakes, so they have been given the name “snakebots.”
But how can such a robot shape be made? A snakebot is built like a chain made of about thirty parts, or modules. Each module is basically the same in that they all have a small computer and a wheel to aid movement. The large computer in the “head” of the snake makes all of the modules in a snakebot work together. The modular design of the snakebot has many advantages. If one module fails, another can be added easily. Snakebot modules can also carry different kinds of tools, as well as cameras. Since each module is actually a robot in itself, one module can work apart from the rest if necessary. That is, all the modules can separate and move on their own, and then later, reconnect back into a larger robot.
Overall, the snakebot design is much simpler than that of common robots. Thus, snakebots will be much less expensive to build. For example, a robot recently sent to Mars cost over a hundred million dollars, whereas snakebots can cost as little as a few hundred dollars.
With their versatility and affordability, snakebots seem to be the wave of the future, at least as far as space robots are concerned.
In which paragraph does the passage compare the cost of snakebots to that of traditional robots?

SMART ENERGY
The upcoming decades will bring significant changes in energy supply and consumption. As some major oil-producing countries have already reached 'peak oil' and concerns about global warming rise, many nations are prioritizing the transition to a low-carbon economy, which will transform electricity supply and usage. [I] Firstly, there will be an increase in overall demand, as consumers switch from oil and gas to electricity to power their homes and vehicles. [II] Secondly, there will be an increase in power generation, not only in terms of how much is generated, but also how it is generated, as there is growing electricity generation from renewable sources. [III] To meet these challenges, countries are investing in Smart Grid technology. [IV] This system aims to provide the electricity industry with a better understanding of power generation and demand, and to use this information to create a more efficient power network.
Smart meters can be integrated with the internet or telephone networks. This connectivity enables customers to control their appliances from a distance. For instance, individuals can turn devices on or off remotely, providing added convenience. Overall, the system offers significant benefits in managing energy usage. By analyzing real-time data, it allows for better decision-making. This technology not only improves efficiency but also supports cost savings. Ultimately, the integration of smart technology will enhance user experience and system management.
The coming decades will bring significant shifts in energy supply and usage. A problem is the fact that many renewable power generation sources are located in remote areas, such as windy uplands and coastal regions, where there is currently a lack of electrical infrastructure. New infrastructures therefore must be built. Thankfully, with improved smart technology, this can be done more efficiently by reducing the reinforcement or construction costs.
Although Smart Technology is still in its infancy, pilot schemes to promote and test it are already underway. Consumers are currently testing the new smart meters which can be used in their homes to manage electricity use. There are also a number of demonstrations being planned to show how the smart technology could practically work, and trials are in place to test the new electrical infrastructure. It is here where Smart Technology is likely to be promoted first, utilising a range of sustainable power sources, transport solutions and an infrastructure for charging electrically powered vehicles. The infrastructure is already changing fast.

DEPENDENCE ON TECHNOLOGY: TIME FOR CHANGE!
[I] Los Angeles dancer, Brian Perez, was eating out with his friends one evening when suddenly everyone went quiet. [II] To his horror, he saw that the reason for this was that people were checking their phones. [III] What if they all put their gadgets in a pile in the middle of the table until they had finished the meal? [IV] If anyone picked up their phone, that person would have to pay the whole bill. And so, it is said, the game of 'phone stacking' was born.
The necessity for action like this highlights a major problem in today's society: our inability to disconnect from technology.
But while Brian's idea deals with the obsession in a social context, measures also need to be taken at home. Some people drop their smartphones into a box the moment they arrive home, which gives them the chance to interact with the people they live with. The fact that the phone cannot be heard - it is on silent - nor seen - the flashing lights are hidden by the box - means that they are no longer tempted to use it.
A less drastic solution is to ban electronic devices at certain times of day when the whole family is likely to be together, for example at meal times. This can be hard for everyone, from teenagers desperate to text friends to parents unable to switch off from work. On a normal day, however, dinner takes less than an hour, and the benefits of exchanging opinions and anecdotes with the rest of the family certainly makes up for the time spent offline.
Taking a break from technology is one thing, but knowing when to turn off a device is another. Time seems to stand still in the virtual world, and before you know it, you find that it is three o'clock in the morning. This is where a digital curfew comes in handy, a set time when all devices must be put away. Evenings without technology are usually nice and peaceful and make a more agreeable end to the day. And then it's time for bed. One of the best ways of ensuring you can sleep at night is to ban electronic devices altogether from the bedroom. Lying next to a machine bursting with information is far from relaxing, and the sounds it emits during the night can easily wake you up. With technology out of the room, a line has been drawn between daytime and sleep time, which enables us to switch off ourselves and drift off to sleep.
According to paragraph 1, Brian Perez was shocked to find that_______.
