You need to read the given passage and construct a question about the information present in the passage. The question should be answerable from the passage. Most importantly, only those questions are allowed whose answers cannot be determined from a single sentence. Do not generate questions that require only a single sentence to answer. Instead, try to combine two sentences and create a question from that combination. Do not create open-ended questions, i.e., the answers to them cannot be found precisely from the information provided in the passage.

Let me give you an example: Paragraph- Sent 1: A Republican bid to keep the government open past Friday includes no new money for the construction of a border wall along the U.S.-Mexico border, according to several congressional aides familiar with ongoing talks.
Sent 2: GOP leaders submitted the new offer Tuesday afternoon in an effort to appease Democrats, whose votes are needed to avert a shutdown of federal agencies, several House and Senate aides said.
Sent 3: However, Republicans also insisted on increases in border security and defense spending, including money to repair existing fencing and new surveillance technology to patrol the nearly 2,000-mile border.
Sent 4: Democrats have indicated that they would support such appropriations so long as no money goes toward an actual wall.
The answer to this example can be: Who has to be appeased to keep the government open?
Here is why: This is a good multi-sentence question because, "appease Democrats" is mentioned in Sent 2, while "keep the government open" is part of Sent 1. As this question requires more than one sentences to answer, it's a good question.

OK. solve this:
Paragraph- Sent 1: (CNN) -- Apple has called it the biggest change to the iPhone since the very first one launched in 2007, but does the latest software, iOS 7, make the iPhone a more compelling buy for travelers than its Android- and Windows-powered competitors?
Sent 2: While iOS 7 sports a significant redesign alongside improved battery life and multitasking ability, it's the assortment of new photo functions that iPhone-toting tourists will find most useful in the iOS 7 update.
Sent 3: The big deal is a faster, easier way to scroll through that endless stream of photos you've amassed over the years and trips.
Sent 4: In previous versions, those photos all existed as part of one, big linear stream.
Sent 5: The iOS7 automatically organizes photos into categories called Collections, Moments and Years, what Apple describes as "smart groupings of your photos and videos based on time and place."Sent 6: Collections is a grouping of moments -- say, a trip to Canada.
Sent 7: Moments are organized according to date and location.
Sent 8: Years are obvious -- groupings of photos by year.
Sent 9: The cool part of the Years organization is a collage of thumbnails of every picture from a given year that appears on the user screen.
Sent 10: This can look a little overwhelming -- the more photos, the more intricate the collage -- but it's actually a handy way to find images quickly.
Sent 11: A redesigned photo Share panel adds a number of functions that users should welcome.
Answer:
How has the photo stream changed from previous versions?
