Some scholars[who?] suggest any labour by children aged 18 years or less is wrong since this encourages illiteracy, inhumane work and lower investment in human capital. Child labour, claim these activists, also leads to poor labour standards for adults, depresses the wages of adults in developing countries as well as the developed countries, and dooms the third world economies to low-skill jobs only capable of producing poor quality cheap exports. More children that work in poor countries, the fewer and worse-paid are the jobs for adults in these countries. In other words, there are moral and economic reasons that justify a blanket ban on labour from children aged 18 years or less, everywhere in the world.

What are the implications for third world countries with regards to child labour?
Answer: low-skill jobs only capable of producing poor quality cheap exports

From the early 1930s eight countries developed radar, these developments were sufficiently advanced by the late 1930s for development work on sound locating acoustic devices to be generally halted, although equipment was retained. Furthermore, in Britain the volunteer Observer Corps formed in 1925 provided a network of observation posts to report hostile aircraft flying over Britain. Initially radar was used for airspace surveillance to detect approaching hostile aircraft. However, the German Wurzburg radar was capable of providing data suitable for controlling AA guns and the British AA No 1 Mk 1 GL radar was designed to be used on AA gun positions.

What did the Observer Corps observe and report on?
Answer: hostile aircraft flying over Britain
