Read the following article and select the best answer. Article: Does your older brother think he's cleverer than you ? Well, he's probably right. According to a new research published in the journal Intelligence, the oldest children in families are likely to have the highest IQs and the youngest the lowest. A number of studies have suggested that IQ scores decline with birth order. In the most recent study, at Vrije University, Amsterdam, researchers looked at men and women whose IQ had been tested at the ages of 5,12 ,and 18. The results , which show a trend for the oldest to score better than the youngest in each test, involved about 200,000 people. That showed that first-borns had a three-point IQ advantage over the second-born, who was a point ahead of the next in line. The order of birth can also affect personality, achievement, and career, with first-borns being more academically successful and more likely to win Nobel prizes. However, eldest children are less likely to be radical and pioneering. Charles Darwin, for example, was the fifth child of six. Exactly why there should be such differences is not clear, and there are a number of theories on environmental influences on the child. The so-called dilution theory suggests that as family resources, both emotional and physical, as well as economic, are limited, it follows that, as a result , as more children come along, the levels of parental attention and encouragement will drop. Another theory is that the intellectual environment in the family favors the first-born who has, at least for some time, the benefit of individual care and help. The theory which enjoys the most support is that the extra time and patience that the earlier-borns get from their parents, compared with those arriving later, gives them an advantage. Question: What is the passage mainly about? - IQ scores have little to do with the order of birth. - Intellectual families favor the first-born - The order of birth can have an effect on IQ - The order of birth can affect personality, achievement, and career.
The order of birth can have an effect on IQ

This was a very different outcome from 1900, when a powerful Gulf Coast hurricane made an unexpected direct hit on Galveston, Texas, killing at least 6,000 people. Vastly improved hurricane warnings explain the different circumstances at either end of the 20th century----residents of Galveston had no advance warning that a storm was approaching, while residents of Biloxi had been warned days in advance, allowing for extensive safety precautions . At the same time that people in Biloxi were thankful for the advance warning, some residents of New Orleans, Louisiana were less satisfied.A day before Georges made landfall, forecasters were predicting that the hurricane had a good chance of striking New Orleans.Because much of New Orleans lies below sea level, the city is at risk for flooding.Emergency management officials must begin evacuations well before a storm strikes.But evacuation costs money: businesses close, tourists leave, and citizens take precautionary measures.The mayor of New Orleans estimated that his city' s preparations for Georges cost more than 50 million.After Georges missed New Orleans, some residents questioned the value of the hurricane forecasts in the face of such high costs. The different views on the early warnings for Hurricane Georges show some of the...
