I'm taking a test and have to guess the right answer to the question after the article. Article: Today's dad spends more hours on childcare than a dad a generation ago.But he still lags behind the modem-day mom,even when her wages are equal,a new study reports.Researchers found that the number of hours a mother spent at work had no effect on the amount of time a father devoted to childcare during the week.Similarly, a mother's income had very little influence on fathers' involvement in childcare.On weekends,however,fathers spent more time with their children.Despite women's increasing role in the labor market, most mothers remain the main caregivers of young children on weekdays. Researchers found that fathers spent all average of 2.5 hours on a weekday and about 6 hours on a weekend day with their children.T _ included time spent playing together or doing schoolwork,personal care such as bathing and feeding.On weekdays, children spent one-third less time with their fathers than with their mothers,but on weekends the time gap closed and kids spent only 13% more time with their mothers than with their fathers.Children of women who made more money spent more time with their fathers on weekends, however."The good news is that as women become equal contributing partners, the involvement of fathers does increase."one researcher said."The bad news is...that men still do less on traditional women's jobs--(taking care of)babies,dishes,etc." In other findings,fathers with some college education spent 17 more minutes per weekday with their children than dads without any college education.Fathers who made more money spent less time with children on weekdays,but the amount of time was fairly small."Our findings suggest that although mothers still shoulder most parenting,fathers' involvement to that of mothers appears to be on the increase,"the researchers conclude."A new father' role is emerging on weekends in families." Question: Which of the following explains a fathers' increasing involvement in childcare? Options: A: Women's liberation movement. B: A mother's income. C: The kind of job fathers do. D: The kind of job women do.

I'm taking a test and have to guess the right answer to the question after the article. Article: If California were not already so famous for Sillicon Valley and Hollywood, it might be well-known for the groups of water-technology firms in its San Diego County. The reverse-osmosis (RO) spiral module, the technique that supports turning seawater and waste-water into drinkable stuff, began in San Diego in 1964. Today dozens of firms in the area supply many of the world's approximately 13,000 RO plants in places from the Persian Gulf and Israel to Australia and China. Southern California itself, however, has not so far been a big user of its own technology. This is surprising, given that the whole American south-west faces a water problem. But now as the climate gets warmer and the population increases, there is more agreement that the existing infrastructure, consisting of vast pipes that carry water from the Sacramento Delta in the north and the Colorado River in the east, will not be enough. In places such as San Diego, which has inadequate and salty groundwater and currently imports 90% or its water, the answers must be greater conservation, reusing as much water as possible, and getting most of the rest from the sea. The first part, conservation, has been widely accepted by the public. San Diego today uses less water with a larger population than it did in 1989, the year water consumption peaked. The second part, water recycling has been a hard sell, because of an unpleasant factor. Americans still use the term "toilet-to-tap" for recycling, even though properly treated waste-water is nowadays completely clean. Singapore made its programme acceptable in part by renaming it as NEWater. This is where desalination comes in, which means taking the salt out of salt water. A firm called Poseidon Resources is now close to building the biggest desalination plant in America behind a power station by the beach in Carlsbad. The power plant sucks in 304m gallons of seawater a day for cooling, so Poseidon plans to change 104m gallons a day by using the RO spiral module. Lots of people like the idea. Once fully... Question: How many solutions to the water problem in San Diego are mentioned in the article? Options: A: 2. B: 3. C: 4. D: 5.

I'm taking a test and have to guess the right answer to the question after the article. Article: Are you a forgetful person? You might be able to blame your genes, a new study in the journal Neuroscience Letters suggests. Researchers from the University of Bonn have identified a variant on the DRD2 gene that seems to be associated with increased forgetfulness. Everyone has one of two variants of the DRD2 gene, the difference is just one letter in the genetic code: Some people have the cytosine (C) variant, while others have the thymine (T) variant. The researchers wanted to see how having one variant over another was associated with forgetfulness. To test this, they analyzed the DRD2 gene of 500 study participants, and also had the participants answer surveys about their forgetfulness (such as how often they misplaced their keys, or forgot names). Most of the study participants--three quarters of them--had the thymine gene variant, while the other quarter had the cytosine gene variant. Researchers found an association between more forgetfulness problems and having the thymine gene variant of DRD2. Meanwhile, the cytosine gene variant seemed to have a protective effect against forgetfulness. However, "there are things you can do to compensate for forgetfulness; writing yourself notes or making more of an effort to put your keys down in a specific location--and not just anywhere," study researcher Dr. Sebastian Markett, of the University of Bonn, said in a statement. Research has also suggested that some age groups are more forgetful than others. A recent national poll showed that millenials, who were born between the early 1980s and the early 2000s, are actually more likely than seniors to be absent-minded with things like what day of the week it is, where they put their keys and remembering to bring their lunch. Meanwhile, another study recently published in the journal BMC Psychology showed that men are more likely than women to experience minor memory problems. Question: We can infer from the study that _ . Options: A: most people have the C gene variant B: about 75% of the study participants are forgetful C: people with the C gene variant are more forgetful D: the T gene variant helps improve people's memory
