Answer the following question: Read the following article and select the best answer. Article: Men have long been puzzled by the amount women pack, when they go on holiday. They despair when they watch their beloved spend much money on extra baggage charge. Nearly half of these women admitted to lying about the weight of their case to their partner before leaving for the airport, in fear of being made to unload some unnecessary items. But it's a fact that women pack more than they need. On average, a woman needs around 57 items in suitcase for a two-week holiday, yet most women pack nearer to 150 items, ranging from skirts, tops, underwear and high heels. In addition, women pack more sun cream, make-up and hair appliances than they were likely to need. They all take up space in the suitcase, only a third of them will see the light of day once at the holiday place. 79 percent of women admitted to taking extra items with them, with the reason for this being "just in case". Women plan their holiday wardrobe months in advance. Packing enough clothes and other items to last a month is not enough for some women. They'd take a chance to shop for new items while holidaying abroad. So they'll return with even more luggage in their cases. Professor Karen Pine said: "Women are tempted to take familiar items with them on holiday, often everything except the kitchen sink. Some people find traveling stressful, particularly when they're unsure about the home comforts available at their holiday place. They over-pack to help cope with those feelings of stress and reduce the uncertainty." This will come as no surprise to some men, who are used to trying to squeeze their partner's luggage into the boot of the car with their own, smaller case. On the other hand, men pack very lightly, with only an average of 40 items for a two-week holiday.
