Directions : Read the following passage and answer the questions as directed. 
The CMIE decided to fill India’s gap in generating fast frequency measures of household well-being in 2014. In its household survey, called the Consumer Pyramids Household Survey (CPHS), the sample size was 172,365 (I) of the official National Sample Survey Organisation (NSSO), which was 101,724. In both surveys, the sample selection method has been broadly the same. 
The CPHS is comprehensive, surveying its entire sample every four months. Each survey is a wave. The CPHS is also a continuous survey, and so, for example, three waves are completed in a year. The CMIE’s CPHS thus has a much larger sample and is conducted at a much higher frequency than the NSSO’s. 
Further, the CPHS is conducted as face-to-face interviews necessarily using GPS-enabled smartphones or tablets. Intense validation systems ensure high fidelity of data capture. All validations are conducted in real-time while the teams are in the field. The data capture machinery (II) high quality data in real time obviating the need for any further “cleaning”, post field operations. 
Once the data is collected and validated in real-time, it is automatically deployed for estimations without any human intervention. In 2016, the CMIE added questions regarding employment/unemployment to the CPHS. Since then, the CMIE has been generating labour market indicators regularly and (III) available for public use.
