What planet would have no advantage of any kind over earth for making parallax measurements?
You have to ask yourself what is an advantage when parallax measurements are being made? . . parallax happens when you move to a different place and the object you see look a little different, the closest ones appear to have moved more than the ones that are further away. In astronomy parallax is created when the Earth is in opposite points of its orbit. Stars that are close appear to have moved a little, relative to the mass of stars that are a long distance away. Parallax was not observed before the 19th century, and the lack of parallax was always used to 'prove' that the Earth could not possibly be going round the Sun. It was only in the 19th century that parallax was observed, but it was only very tiny movements of the closest stars. It forced people to realise that the stars are incredibly far away and the Earth does go round the Sun after all, so it was extra evidence of the Sun being at the centre of the solar system. A parallax measurement is easier to make if the baseline is longer, so the answer to your question is that Mercury and Venus have no advantage for making parallax measurements.

What is a displacement time?
The time it takes for some amount of displacement to occur could be said to be the displacement time. Let's say we observe a displacement event, and we know the mass of the object and something about the resistance it encounters. We can discover something about the force causing that displacement if we know how long it took (the displacement time) for the whole thing to happen. We can also calculate acceleration, speed, and stuff like that, too.

Why the same galaxy can appear to have different shapes to different observers?
It can appear to have different shapes because of the viewers point of view. Also Parallax can have an affect on it! Google it for further research look up Galaxy Parallax. Glad I Could help! Another opinion: All observers see the same shape of any galaxy, and no galaxy exhibits parallax, as long as we're talking about observations taken anywhere in our solar system.
Explain how the displacement of an object could be zero while the distance traveled was 150 miles?
Displacement is only the distance from the starting point. As long as you return to where you started, then you can travel 1.0 x 10^999999999999 miles and still have a displacement of zero.
