Answer:
C. Gender of the fetus.
Explanation:
Leopold's maneuvers are a series of actions that the obstetrician performs touching the woman's belly to determine the position of the fetus, the number of fetuses, and the degree of the presenting part's descent into the pelvis. The gender of the fetus can not be determined by touching the abdominal area, only an ultrasound can determine it.

You shouldn't approach a horse from behind them, because they can't see you.
<span>The usual answer (and correct) is to improve on the insulation, for example by covering the calorimeter, and using two cups, one inside the other.
Further improvements can be made
1) carrying out the experiment over as short a period of time as possible. reason; any calorimeter will loose heat, but the shorter the time allowed, the less heat will be lost.
2) Use a larger calorimeter, with greater volume of solution. reason; the greater the solvent mass requires more energy to obtain the same change in temperature. You get a smaller temp change for the same reaction, so less losses to the surroundings.
3) calibrate your calorimeter heat the same volume of pure water to a similar temperature as that which the reaction produces. Then determine the rate of heat loss over a period of time, say take temp every minute for 30 minutes, and plot a graph. This will give you a calibration curve that you can use to apply a correction for your calorimeter.</span>
