Explanation:

Rare Earth Elements are called 'rare earth' because earlier it was difficult to extract them from their oxides forms technologically. 

• They occur in many minerals but typically in low concentrations to be refined in an economical manner.
• China at one point produced 90% of the rare earths the world needs.Today, however, it has come down to 60% and the remaining is produced by other countries, including the Quad (Australia, India, Japan and United States).
• So the dominant share of processed Rare Earths lies with China. 
• They are a set of seventeen metallic (not the non-metallic) elements. These include the fifteen lanthanides on the periodic table in addition to scandium and Yttrium that show similar physical and chemical properties to the lanthanides. They are also called the rare-earth metals. 

Hence both statements 1&3 are correct.
