Answer

Brief Explanations:

Mercury and Venus have smaller semi - major axes ($A$) than Earth, so they are closer to the sun. Planets closer to the sun have shorter orbital periods ($T$). Also, the further a planet is from the sun (larger $A$), the longer its orbital period (longer $T$), which means the longer its orbit is.

Answer:

Mercury and Venus are closer to the sun than Earth is. So, their orbital periods are shorter than Earth's orbit. The further a planet is from the sun, the longer its orbit is.
