How to reduce the length of a vector?

Dear all,

I have A which is 8x2 vector

A = [185 194; 155 208; 152 244; 174 258; 214 257; 223 236; 220 211; 215 198];

I want to generate B which is 50% of A by selecting every other pair.

B = [185 194; 152 244; 214 257; 220 211];

Any idea how to generate B?

Any idea will be appreciated.
