Consider the following statements regarding base-line measurements :
1. Very precise measurement can be done only on densely cloudy days or at nights.
2. Error due to application of non-standardised pull on the tape can be either cumulative or compensating type.
3. Intermediate obstructions in the measurement of base-lines can be cleared by erecting towers.

In each of the following examples certain quantity of work 'W' is done.
1. The point of application of a force of (50i + 60j + 80k) in kN units moves through a distance given by (6i + 5j + 2.5k) in metres.
2. A pump raises 2m³ of water through a height of 20 m (Take g = 10 m/s²).
3. A shaft delivering a torque = 200 kNm makes 0.75 revolution.
4. A couple (30i - 20j + 100k) in kNm units acting on a body rotates it through an angular displacement of (2i + 3j + 6k) radians.
The correct sequence of these quantities of work 'W' arranged in order of their increasing magnitude is
