Question

Which selection query will NOT work in GIS?

a) 'Density'<200
b) 'Area' > '5 Acre'
c) 'Pollution' = 'Low'
d) 'City_name' <> 'Urbana'
e) 'Population' > 50000

Answer 1

The selection query that will NOT work in GIS is option b) 'Area' > '5 Acre'. In a GIS, it is not possible to compare a string of text with a numeric value. To fix this, the quotes around '5 Acre' should be removed and the field 'Area' should contain numeric values.

Step-by-step explanation:

The selection query that will NOT work in GIS is option b) 'Area' > '5 Acre'.

In a GIS (Geographic Information System), it is not possible to compare a string of text ('Area') with a numeric value ('5 Acre'). The comparison operator used ('>') is also invalid for this type of query.

To fix this, you would need to remove the quotes around '5 Acre' and make sure that the field 'Area' actual contains numeric values, such as the area in square meters.
