Problem: Carnival:

Carnival in Haiti started in 1804 in the capital Port-au-Prince after the declaration of independence. The Port-au-Prince Carnival is one of the largest in North America. It is known as Kanaval in the Creole language. It starts in January, known as "Pre-Kanaval", while the main carnival activities begin in February. In July 2012, Haiti had another carnival called Kanaval de Fleur. Beautiful costumes, floats, Rara parades, masks, foods, and popular rasin music (like Boukman Eksperyans, Foula Vodoule, Tokay, Boukan Ginen, Eritaj, etc.) and kompa bands (such as T-Vice, Djakout No. 1, Sweet Micky, Kreyol La, D.P. Express, Mizik Mizik, Ram, T-Micky, Carimi, Djakout Mizik, and Scorpio Fever) play for dancers in the streets of the plaza of Champ-de-Mars. An annual song competition takes place.

Problem: Cotton:

Cotton lisle is a finely-spun, tightly twisted type of cotton that is noted for being strong and durable. Lisle is composed of two strands that have each been twisted an extra twist per inch than ordinary yarns and combined to create a single thread. The yarn is spun so that it is compact and solid. This cotton is used mainly for underwear, stockings, and gloves. Colors applied to this yarn are noted for being more brilliant than colors applied to softer yarn.

Problem: Windows 8:

Retail distribution of Windows 8 has since been discontinued in favor of Windows 8.1. Unlike 8, 8.1 is available as "full version software" at both retail and online for download that does not require a previous version of Windows in order to be installed. Pricing for these new copies remain identical. With the retail release returning to full version software for Windows 8.1, the "Personal Use License" exemption was removed from the OEM SKU, meaning that end users building their own PCs for personal use must use the full retail version in order to satisfy the Windows 8.1 licensing requirements. Windows 8.1 with Bing is a special OEM-specific SKU of Windows 8.1 subsidized by Microsoft's Bing search engine.

What is the primary difference in Windows 8.1?
---
A: 8.1 is available as "full version software"

Problem: Sahara:

The central Sahara is estimated to include five hundred species of plants, which is extremely low considering the huge extent of the area. Plants such as acacia trees, palms, succulents, spiny shrubs, and grasses have adapted to the arid conditions, by growing lower to avoid water loss by strong winds, by storing water in their thick stems to use it in dry periods, by having long roots that travel horizontally to reach the maximum area of water and to find any surface moisture and by having small thick leaves or needles to prevent water loss by evapo-transpiration. Plant leaves may dry out totally and then recover.

what desert area has 500 species of animals?
