The rank of 2nd Lieutenant/Act. Sub Lieutenant/Pilot Officer were removed because the salary of the officers holding these ranks were less compared to senior Non-Commissioned Officers i.e Subedar Major in army, Master Warrant Officer in air force and Master Chief Petty Officer -1st Class in navy.

Rest of the statements are incorrect.In modern armies, lieutenant general normally ranks immediately below general and above major general; it is equivalent to the navy rank of vice admiral, and in air forces with a separate rank structure, it is equivalent to air marshal.

Error is in third part. Since “doing” was used in second part it should be followed by “doing” in third part as well instead of using “done”. Such repetitive figure of speech is used in
English grammar to create emphasis. This sentence indicates that a thing that is worth doing is also worthy of doing well. Here worth is the noun that must be followed by the verb doing.

The error is in first part. ‘Tell’ should be replaced with ‘Ask’. Tell is a command whereas Ask is a request and hence more courteous in this case. As this is a request the sentence should start with ‘Ask’ rather than ‘tell’.
