It'a binary classification problem, you should choose the answer between supported and refuted. Table cells in one row are seperated by '|', and different rows are seperated by '
'.

Table:
| chemical class | group | formula | prefix | suffix | example |
| haloalkane | halo | rx | halo - | alkyl halide | chloroethane (ethyl chloride) |
| fluoroalkane | fluoro | rf | fluoro - | alkyl fluoride | fluoromethane (methyl fluoride) |
| chloroalkane | chloro | rcl | chloro - | alkyl chloride | chloromethane (methyl chloride) |
| bromoalkane | bromo | rbr | bromo - | alkyl bromide | bromomethane (methyl bromide) |
| iodoalkane | iodo | ri | iodo - | alkyl iodide | iodomethane (methyl iodide) |
