QUES: Madonna's look and style of dressing, her performances, and her music videos influenced young girls and women. Her style became one of the female fashion trends of the 1980s. Created by stylist and jewelry designer Maripol, the look consisted of lace tops, skirts over capri pants, fishnet stockings, jewelry bearing the crucifix, bracelets, and bleached hair. Madonna achieved global recognition after the release of her second studio album, Like a Virgin, in November 1984. It topped the charts in several countries and became her first number one album on the Billboard 200. The title track, "Like a Virgin", topped the Billboard Hot 100 chart for six consecutive weeks. It attracted the attention of organizations who complained that the song and its accompanying video promoted premarital sex and undermined family values, and moralists sought to have the song and video banned.

How long did "Like a Virgin" stayed on the Billboard 100?
What is the answer?
ANS: six consecutive weeks
QUES: The Early Cretaceous spans from 145 million to 100 million years ago. The Early Cretaceous saw the expansion of seaways, and as a result, the decline and extinction of sauropods (except in South America). Many coastal shallows were created, and that caused Ichthyosaurs to die out. Mosasaurs evolved to replace them as head of the seas. Some island-hopping dinosaurs, like Eustreptospondylus, evolved to cope with the coastal shallows and small islands of ancient Europe. Other dinosaurs rose up to fill the empty space that the Jurassic-Cretaceous extinction left behind, such as Carcharodontosaurus and Spinosaurus. Of the most successful would be the Iguanodon which spread to every continent. Seasons came back into effect and the poles got seasonally colder, but dinosaurs still inhabited this area like the Leaellynasaura which inhabited the polar forests year-round, and many dinosaurs migrated there during summer like Muttaburrasaurus. Since it was too cold for crocodiles, it was the last stronghold for large amphibians, like Koolasuchus. Pterosaurs got larger as species like Tapejara and Ornithocheirus evolved.

What species was most similar to crocodiles?
What is the answer?
ANS: unanswerable
QUES: Infrared tracking, also known as infrared homing, refers to a passive missile guidance system, which uses the emission from a target of electromagnetic radiation in the infrared part of the spectrum to track it. Missiles that use infrared seeking are often referred to as "heat-seekers", since infrared (IR) is just below the visible spectrum of light in frequency and is radiated strongly by hot bodies. Many objects such as people, vehicle engines, and aircraft generate and retain heat, and as such, are especially visible in the infrared wavelengths of light compared to objects in the background.

What is the term that uses the infrared spectrum that is radiated by hot bodies?
What is the answer?
ANS:
unanswerable
