Question: (CNN) -- Chris Froome conquered Mont Ventoux at the Tour de France to extend his overall lead with a week remaining in cycling's most prestigious race.

In a fascinating battle Sunday, Team Sky's Froome caught and then passed Nairo Quintana during the steep 13-mile climb to give him a four-minute cushion over his nearest rivals.

A spent Froome had to be given oxygen when the 15th stage -- the longest of this year's Tour at 150 miles -- ended but he'll get a chance to recover during Monday's day off.

On Bastille Day French hopes were dashed, as Sylvain Chavanel lost his lead to Movistar's Quintana before the Colombian faded and Froome charged.

"I thought he'd be less strong than he was," Quintana told the Tour's website.

Froome has now won both stages with summit finishes.

"I didn't expect to win," Britain's Froome said after nearly six hours of racing. "I wanted to get more of a buffer on the general classification but I didn't think I could go for the win.

"Quintana is a very strong climber and I wasn't expecting him to go from as far as he did but hats off to him. He did a great ride and he showed how strong he is."

Despite the gruelling end to the stage, Froome and Quintana -- one to watch for the future -- had time for a quick chat.

"In the last (1.2 miles) he was fading a little and I still had a little bit left," said Froome. "I was just trying to say, 'Man, come on just a little bit more, we're almost there.' But he was slipping behind. 1. Who's now in the lead?

input: The World Health Organization warns that millions of people are dying every year from indoor air pollution. The WHO finds that poor cooking, heating and lighting technologies are killing millions of people each year.

Indoor air pollution results from the use of dangerous fuels and cook-stoves in the home. To help fight the problem, the WHO announced, new guidelines aimed at reducing household pollutants.

WHO officials say nearly three billion people are unable to use clean fuels and technologies for cooking? heating and lighting. And they say more than seven million people die from exposure to indoor or outdoor air pollution each year. Of that number, the WHO says about 4. 3 million people die from household air pollution given off by simple coal cook-stoves. Most of the deaths are in developing countries.

Carlos Dora is Coordinator in the WHO's Department of Public Health, Environmental and Social Determinants of Health. He says people should not use unprocessed coal and kerosene fuel indoors. He says opening a window or door to let out the harmful air will not improve the situation. It will only pollute the outdoors.

WHO officials say indoor pollution leads to early deaths from stroke, heart and lung disease, childhood pneumonia and lung cancer. Women and girls are the main victims. The United Nations found that more than 95 percent of households in sub-Saharan Africa depend on solid fuels for cooking. It says huge populations in India, China and Latin American countries, such as Guatemala and Peru, are also at risk.

Nigel Bruce is a professor of Public Health at the University of Liverpool. He says researchers are developing good cook-stoves and other equipment to burn fuels in a more efficient way.

WHO experts note some new, safe and low-cost technologies that could help are already available. In India, you can buy an induction stove for about $ 8.00. And in Africa a you can buy a solar lamp for less than $ 1. 00. 1. How many die annually from indoor air pollution?
