[EX Q]: Article: After commuting, cooking dinner and doing household chores, the average parent has just 30 minutes to devote to their children in the evenings, according to a new study. One in four working parents worry that half an hour simply isn't enough, while almost half fret that they aren't a good enough parent during the week. However, parenting experts believe just 12 minutes a day may be enough for mothers and fathers to fully _ with their child -- as long as they ask the right questions. Child psychologist Dr Claire Halsey said asking a series of open-ended questions can help improve parents' relationship with their children. Among the questions recommended in the research are: "How many times have you smiled today -- what made you laugh?"; "Can you act out what you did at breaktime?"; "Who is taller -- mummy or your teacher?" and "What are the names of the toys you played with today?" Parents of older children are advised to start up a conversation with: "I've got a great story for you but I want one in return... you first!" or "Tell me some school gossip ... _ !" Dr Halsey, working with the makers of Ribena Plus, who commissioned the research, said: "There is no one as tough on their own parenting skills as a parent -- but this study shows there is no need for parents to be so harsh. It's hard for working parents to juggle all their responsibilities and it can feel like guilt is simply a parent's lot -- but it's absolutely not. By using clever tactics such as a little preparation alongside use of open-ended questions -- such as 'Tell me what the best bit about your day was?' -- parents can reduce the time worrying about chores and work and spend more time learning about their children's day."

[EX Q]: Article: It is amazing to note that the Internet is still such a new device, and yet it is one of the fastest and most powerful media tools. But think about it for a moment. On the Internet, a big online company can be run by two guys out of their garage. So it is only reasonable that people shopping on the Net would be a little _ of the security levels. Internet giants such as Microsoft knew consumer confidence was the key to getting virtual shopping off the ground, and they work hard to make people feel safe to shop online. Credit card companies, too, quickly saw the potential for Internet shopping, and have installed things like online shopping insurance for people. If you ever have a problem with your online credit purchases, many credit card companies will happily refund your money and then set their claws on the company that wronged you. Now that's buying power! There are other bonuses for online shoppers, of course. No line-ups, for one. No annoying mall shopping carts with broken wheels and kids crying because their parents won't get them what they want. When shopping online, consumers can sit down, have a coffee, and wear their slippers, not have to worry about their hair or parking and just click through sale after sale. Comparison shopping couldn't be any easier. And thanks to courier companies getting in on the act, you never need wait longer than a day or two to get those all important purchases delivered right to your door. No wonder so many companies are shaking their heads at traditional advertising and instead looking to the "virtual" world to attract online shoppers.
Question: _ leads to consumers' trust in online shopping.
Options: (A) Shopping law (B) Shopping convenience (C) Internet access (D) Shopping security
