In one sentence, describe what the following article is about: Fumes from stain or varnish can be harmful to breathe. If the room you’re working in has external windows, open these as wide as possible. If you’d like to take a further safety precaution, rent a vapor-rated respirator  and wear it while you’re staining the pine floor.  You can rent a vapor-rated respirator at a local hardware or home supply store. Since you’ll be working with the windows open, it’s advisable to finish the pine flooring on a warm, rain-free day. If you are not impressed with the natural color of the pine flooring and would like to darken it, you can purchase a stain to seal and darken the pine. Visit your local paint store and ask to peruse their stain selection. Speak with the sales staff to determine which brand and variety of stain is best for your flooring, considering its location in your house and the amount of use it will receive. The major difference between stain and varnish is that varnish will dry clear while stain will darken the color of your flooring. So, if you prefer the natural color of the pine flooring and just want to seal it to protect against moisture and scratches, opt for a varnish. Unlike oil, varnish adheres to the top of the wood without soaking deep into the grain. Consequently, you can remove varnish if you decide to. Oil cannot be removed from wood. Oils are a traditional softwood finish that will penetrate deep into the pine flooring. Oil finishes—unlike many varnishes—won’t peel or flake, and often look better with age. Types of oil commonly used to finish pine floors include:  Tung oil, which has a relatively low level of sheen. This leaves the pine with a more “natural” appearance. Linseed oil, which is tarry and so brings out the grain of the pine. Lemon or walnut oil, which are considered specialty oils and may be more expensive. Before you stain the entire floor, test the stain in an inconspicuous are to make sure that you like the color. Apply the stain using a 3 in (7.6 cm) paintbrush. Let the stain dry for 24 hours.  If you like the appearance of the stained sample patch, you can proceed with staining the entire floor. If you don’t like the appearance of the stained wood, select a different colored stain. Or, if you realize that you prefer the natural color of unstained pine, opt for a clear varnish instead.
Summary: Ventilate your working area. Choose a color of stain if you’d like to darken the pine floor. Select a clear varnish if you prefer not to alter the pine’s coloring. Apply a colorless oil to preserve the pine’s natural color. Test the stain out on a small corner of flooring.

Problem: Article: The bride and groom or the groom's parents will have sent you an invitation noting the details of the rehearsal dinner. In addition to the time and date of the event, some invitations note the style of dress the hosts wish for guests to wear. Here are some of the different styles of dress you may see listed on a rehearsal dinner invitation:  Black tie. This style is more common for the actual wedding day, but you may see a request for black tie attire on a rehearsal dinner invitation. Men should wear a tuxedo to a black tie event, while women should wear a cocktail dress or long evening gown. Formal or black tie optional. A formal or black tie optional event indicates that the suggested attire is slightly less formal than a black tie event. Men may wear a tuxedo, but could also wear a dark suit and tie. Women may wear a cocktail dress, dressy suit or evening gown. Dress for a "beach formal" event. If the invitation states that the rehearsal dinner is beach formal, be prepared for an elegant event held outdoors. Guests should dress for the elements, including sun and sand. Men may wear a lightweight suit with a linen shirt, or khaki or linen pants with a cotton button-down shirt. Ties typically are not required at beach formal events. Women may wear a tea-length or knee-length sundress. Select appropriate attire for a "semi-formal" or "dressy casual" rehearsal dinner. For men, semi-formal attire indicates a suit and tie. A dark suit is recommended for evening events, while lighter colors may be appropriate for a daytime event. However, as most rehearsal dinners are held in the evening, darker colors are recommended. Women may wear a cocktail dress or a dressy skirt and top to a semi-formal dinner. Dress for a "casual" event. While casual dress to some people may mean jeans and shorts, in most cases that is not appropriate attire for a rehearsal dinner unless specifically noted on the invitation. Men should wear dress pants with a polo or button-down shirt to a casual rehearsal dinner. Women should wear a dress, or skirt or pants with a dressy blouse. If the invitation doesn't state what type of attire to wear, there are other clues to examine. You can determine a lot about how to dress based on the time of day the dinner is taking place. If it's on the earlier side, say 5:00 pm, it's probably more of a happy hour or cocktail hour, which would imply less formal dress than a full dinner beginning at 7 or so.  Some rehearsal meals are not dinners, but lunches or brunches. If this is the case, the attire will probably be slightly less formal. The time alone is not usually enough to give you a clear indication of what to wear, so take other factors into account along with this one. This is probably the most important factor to take into account when you're deciding what to wear. Fine restaurants may have a dress code, requiring men to wear jackets and ties, for example. More casual establishments won't have a dress code, and neither will most outdoor functions. In these cases you'll have to use your own discretion to figure out what's appropriate to wear. The wedding theme can indicate appropriate rehearsal dinner attire. In general, select rehearsal dinner attire similar to the wedding attire, except less elegant. For example, a beach wedding will likely have a relaxed atmosphere at the rehearsal dinner, which would suggest sundresses for women and slacks with polo shirts for men. A very traditional wedding might suggest classic semi-formal attire for the rehearsal dinner, such as suits for men and cocktail dresses for women. If specified on the invitation, the type of food served can indicate the formality of the event. For example, a clambake on the beach may suggest casual attire, while a five-course meal may suggest semi-formal attire. If you're worried there's a dress code and you aren't sure what it is, it's perfectly fine to call either the venue or the host to find out what will be appropriate. There's no need to go into great detail about what you intend to wear; just ask whether the event will be formal, semi-formal, or informal. After that, it's up to you to pick out the right outfit.
Summary:
Check the invitation for dress details. Note the time of the dinner. Note the location of the dinner. Consider the theme of the wedding. Determine the appropriate attire based on the rehearsal dinner menu. Call the venue or hosts if you still aren't sure.
