How can the parallax error be avoided?
By looking at the object straight, instead of from either side?
How can parallax error be avoided?
To help the user avoid this problem, the scale is sometimes printed above a narrow strip of mirror, and the user positions his eye so that the pointer obscures its own reflection. This guarantees that the user's line of sight is perpendicular to the mirror and therefore to the scale. Parallax is thus avoided.
Parallax error how it can be avoided?
I'm assuming you're measuring somethings' displacement along a scale. There are three simple ways of reducing parallax error in that case: 1: Attach a straight object (like a ruler or straightened paperclip) to the thing you're measuring the displacement of, it should stick out of the object perpendicularly to the scale you're measuring the displacement on. 2: Make sure that object is as close to your scale as possible, but not touching. 3: Put your eyes level with the object, and as close to it as you safely can.
Which dimensioning method permits the accumulation of errors and should be avoided?

Parallax would be easier to measure if?
Parallax would be easier to measure if the Earth were farther from the sun. This way, there will be a wider angle to the stars using the parallax method.
