QUES: At no more than 200 kilometres (120 mi) north to south and 130 kilometres (81 mi) east to west, Swaziland is one of the smallest countries in Africa. Despite its size, however, its climate and topography is diverse, ranging from a cool and mountainous highveld to a hot and dry lowveld. The population is primarily ethnic Swazis whose language is siSwati. They established their kingdom in the mid-18th century under the leadership of Ngwane III; the present boundaries were drawn up in 1881. After the Anglo-Boer War, Swaziland was a British protectorate from 1903 until 1967. It regained its independence on 6 September 1968.
In terms of size where does Swaziland rank within Africa in terms of country size?

ANS: one of the smallest

QUES: The term Hokkien (; hkkn) is itself a term not used in Chinese to refer to the dialect, as it simply means Fujian province. In Chinese linguistics, these dialects are known by their classification under the Quanzhang Division (Chinese: ; pinyin: Quanzhang pian) of Min Nan, which comes from the first characters of the two main Hokkien urban centers Quanzhou and Zhangzhou. The variety is also known by other terms such as the more general Min Nan (traditional Chinese: , ; simplified Chinese: , ; pinyin: Minnanyu, Minnanhua; Peh-oe-ji: Ban-lam-gi,Ban-lam-oe) or Southern Min, and Fulaohua (traditional Chinese: ; simplified Chinese: ; pinyin: Fulaohua; Peh-oe-ji: Ho-lo-oe). The term Hokkien (Chinese: ; Peh-oe-ji: hok-kian oe;Tai-lo:Hok-kian-ue), on the other hand, is used commonly in South East Asia to refer to Min-nan dialects.

QUES: In infrared photography, infrared filters are used to capture the near-infrared spectrum. Digital cameras often use infrared blockers. Cheaper digital cameras and camera phones have less effective filters and can "see" intense near-infrared, appearing as a bright purple-white color. This is especially pronounced when taking pictures of subjects near IR-bright areas (such as near a lamp), where the resulting infrared interference can wash out the image. There is also a technique called 'T-ray' imaging, which is imaging using far-infrared or terahertz radiation. Lack of bright sources can make terahertz photography more challenging than most other infrared imaging techniques. Recently T-ray imaging has been of considerable interest due to a number of new developments such as terahertz time-domain spectroscopy.
What is the technique that involves imaging with terahertz radiation?

ANS:
'T-ray' imaging
