Here is a question about this article: Under the supervision of May and Taylor, numerous restoration projects have been under way involving Queen's lengthy audio and video catalogue. DVD releases of their 1986 Wembley concert (titled Live at Wembley Stadium), 1982 Milton Keynes concert (Queen on Fire Live at the Bowl), and two Greatest Video Hits (Volumes 1 and 2, spanning the 1970s and 1980s) have seen the band's music remixed into 5.1 and DTS surround sound. So far, only two of the band's albums, A Night at the Opera and The Game, have been fully remixed into high-resolution multichannel surround on DVD-Audio. A Night at the Opera was re-released with some revised 5.1 mixes and accompanying videos in 2005 for the 30th anniversary of the album's original release (CD+DVD-Video set). In 2007, a Blu-ray edition of Queen's previously released concerts, Queen Rock Montreal & Live Aid, was released, marking their first project in 1080p HD.

The problem: Answer a question about this article:
During childhood, siblings are a source of conflict and frustration as well as a support system. Adolescence may affect this relationship differently, depending on sibling gender. In same-sex sibling pairs, intimacy increases during early adolescence, then remains stable. Mixed-sex siblings pairs act differently; siblings drift apart during early adolescent years, but experience an increase in intimacy starting at middle adolescence. Sibling interactions are children's first relational experiences, the ones that shape their social and self-understanding for life. Sustaining positive sibling relations can assist adolescents in a number of ways. Siblings are able to act as peers, and may increase one another's sociability and feelings of self-worth. Older siblings can give guidance to younger siblings, although the impact of this can be either positive or negative depending on the activity of the older sibling.
At what stage to mixed-sex siblings generally experience an increase in intimacy?
****
The answer: middle adolescence

The problem: Answer a question about this article:
Zinc is a bluish-white, lustrous, diamagnetic metal, though most common commercial grades of the metal have a dull finish. It is somewhat less dense than iron and has a hexagonal crystal structure, with a distorted form of hexagonal close packing, in which each atom has six nearest neighbors (at 265.9 pm) in its own plane and six others at a greater distance of 290.6 pm. The metal is hard and brittle at most temperatures but becomes malleable between 100 and 150 C. Above 210 C, the metal becomes brittle again and can be pulverized by beating. Zinc is a fair conductor of electricity. For a metal, zinc has relatively low melting (419.5 C) and boiling points (907 C). Its melting point is the lowest of all the transition metals aside from mercury and cadmium.
Is iron more dense than zinc?
****
The answer:
It is somewhat less dense than iron
